Migrate the backend from pip to uv

Replace requirements.txt with a uv workspace and lockfile, install the five tavolo packages from packages/* in development and non-editable in the image, and build the Docker image with uv. Move dev tools to a PEP 735 dependency group and refresh the locked dependency versions.

+## PWA
+
+The frontend is an installable PWA: `web/manifest.webmanifest` describes
+the app (standalone display, felt theme colors, PNG icons), and `web/sw.js`
+is a caching-free service worker — it deliberately caches nothing, since
+live state always comes from the server and hashed asset names change every
+build — that also handles clicks on move notifications. Browsers offer to
+install Tavolo over HTTPS (or on localhost in development).
+
+Both files must be served from the site root, or the worker's scope and the
+manifest's `start_url` could not cover the app: Granian only serves
+`/static` and `/assets`, so `tavolo/static.py` answers
+`/manifest.webmanifest` and `/sw.js` (revalidated on every load) from the
+same build directory as the shell. Icons are committed under
+`web/assets/icons/`; `web/make-icons.sh` regenerates them with
+`rsvg-convert` after editing the vector sources.
+
+## Move notifications
+
+Players can opt into desktop notifications for the other players' card
+plays with the bell in the game HUD (the first click asks for the browser
+permission; the preference is stored per device and applies to every
+game). Notifications only appear while the game tab is in the background
+or its window is unfocused — never while the player is watching the table
+— and only for games the viewer is seated in, never for their own plays.
+They are delivered through the service worker (so installed PWAs get them
+too) under a per-game tag, which replaces the previous move instead of
+stacking one notification per play; clicking one focuses the game tab.
+The game page must stay open to receive them, since that is where the
+live-play websocket lives.

+- 40-card Italian deck; three cards per player and four cards face up on
+  the table at the start of every hand. When every hand is empty the
+  dealer deals three more cards to each player (no new table cards) until
+  the deck is exhausted: two players play six rounds per hand, four
+  players three.
+- A card captures a **single card of equal rank** (mandatory when present)
+  or a **combination of table cards whose ranks sum to its own**; when any
+  capture exists it must be taken. Remaining table cards at the end of the
+  hand go to the player who made the last capture.
+- Emptying the table scores a *scopa* (+1), except on the last play of the
+  hand (a sweep on the last play of a round still scores when the deck has
+  cards left).
+- Hand points: `carte`, `denara`, `settebello` and `primiera` (same values
+  and all-four-suits requirement as scopone), plus one point per scopa.
+  Ties award nothing. There is no napola.
+- Optional *asso pigliatutto* rule (per-game `asso_pigliatutto` creation
+  option, default off; scopa d'assi): an ace played when no equal rank is
+  on the table sweeps every card on the table — or captures itself when
+  the table is empty. The capture never scores a scopa, but it counts as
+  the last capture, and the mandatory equal-rank capture still applies
+  when another ace is on the table.
+- The match ends when a side reaches the target score (default 11 points
+  for two-player scopa and 21 for scopa a quattro, the traditional
+  partnership target; configurable per game via the `target_score`
+  creation option) with a clear lead; a tie at or above the target is
+  broken by another hand.
+- `scopa` is the classic two-player game; `scopa_a_quattro` seats four
+  players in two fixed partnerships (seats 0/2 vs 1/3, partners
+  opposite).

+### Briscola chiamata
+
+- 40-card Italian deck, eight cards each for five players: the whole deck
+  is dealt, so there is no stock and no face-up card.
+- The calling auction starts with the player after the dealer: each
+  player either passes (leaving the auction) or bids a lower rank than
+  the standing bid (*A > 3 > K > H > J > 7 > 6 > 5 > 4 > 2*); once the
+  standing bid is the two, the auction continues on points (62, 64, …).
+  The last player standing must bid, so every deal gets a caller.
+- The winner names any card of the won rank. If the winner holds it, the
+  caller plays alone against the other four; otherwise its holder is the
+  secret partner and the two form the calling side. The called card's
+  suit is the trump; the partner's identity stays hidden until the
+  called card is played.
+- Play and trick resolution follow briscola; eight tricks exhaust every
+  hand. The calling side must reach the declared target (61 unless
+  raised); with the plain target a 60–60 deal is a *patta* and is
+  replayed with the next dealer. A match is a single deal, so the caller
+  and partner (or the lone caller) against the other players map onto
+  the platform's two-team result, Elo and history.
+- Auction turns, the called-card choice and the plays all have their own
+  `TURN_TIMEOUT_SECONDS` deadlines: an absent bidder passes, the last
+  player standing with no bid is made to bid the ace, an absent winner's
+  call names a random suit of the won rank, and plays are auto-played.

 ## Development
 
+The backend is a [uv](https://docs.astral.sh/uv/) workspace: `pyproject.toml`
+declares the five packages under `packages/` as members, and `uv.lock` pins
+their full dependency closure. The checked-in `.python-version` selects
+Python 3.14, matching the Docker image. Install uv, then from `server/`:

 ```
 
+`uv sync` installs the workspace's `dev` dependency group (`mypy`,
+`httpx-ws`) automatically; pass `--no-dev` for a runtime-only environment.
+The `otel` extra is optional, but without it the telemetry integration tests
+skip. The lockfile is committed: use `uv lock --upgrade` (or
+`uv lock --upgrade-package <name>`) to update dependencies deliberately.

+
+Briscola chiamata is the five-player variant of briscola. The 40-card
+deck is dealt out entirely (8 cards each, no stock): there is no face-up
+briscola card. Instead the players auction off the right to call a
+partner:
+
+* starting with the player after the dealer, each player either passes
+  (leaving the auction for good) or bids a rank lower than the standing
+  bid on the ladder ``A > 3 > K > H > J > 7 > 6 > 5 > 4 > 2``; the first
+  bidder may bid any rank. Once the standing bid is the 2, further bids
+  raise the points the calling side must reach instead (62, 64, ...).
+* the last remaining bidder wins and names the exact card of the winning
+  rank (any suit). If the winner holds the named card they play alone
+  against the other four; otherwise its holder is the **secret partner**
+  and the two form the calling side. The called card's suit is the trump
+  (*briscola*) for the whole deal.
+* play and scoring follow briscola. The calling side must reach the
+  declared target (61 unless raised); a 60-60 deal with the plain target
+  is a **patta** and is replayed.
+
+A match is a single deal (patta replays aside), so the two sides map
+onto the platform's two-team result (Elo rating, match history). The
+partner's identity stays hidden until the called card is played, at
+which point the roles are revealed.

 ## Adding a game
 
 Implement `GameEngine` (see `engine.py` for the full contract), register
 it in a `GameRegistry`, and mount `PlatformMixin(Platform(...))` on a
 `KayaApp` — see the composition root in `tavolo.app`. The canonical
-examples are [`tavolo-scopone`](../tavolo-scopone/README.md) and
+examples are [`tavolo-scopone`](../tavolo-scopone/README.md),
+[`tavolo-scopa`](../tavolo-scopa/README.md) and

+
+Scopa — the classic Italian fishing game — in its two-player form and in
+the four-player fixed-partnership variant (*scopa a quattro*), as
+[`tavolo-platform`](../tavolo-platform/README.md) game implementations.
+The optional *asso pigliatutto* creation option turns either variant into
+**scopa d'assi**.
+
+## Contents
+
+- `state.py` — `ScopaState` (pure game data: phases, players, hands,
+  table, the deck persisting between rounds, scores, deadlines),
+  `PlayerState`, `Card`, `Move`, with JSON (de)serialization. No session
+  envelope, no transport, no I/O.
+- `engine.py` — the pure rules engine: deck, legal captures, plays,
+  auto-play, round re-dealing, hand scoring (carte, denara, settebello,
+  primiera, scope), the optional asso pigliatutto capture, hand-end
+  acknowledgements. Deterministic and I/O-free apart from logging, so the
+  whole rule set is unit-testable.
+- `errors.py` — scopa-specific errors (`CardNotInHand`); every other
+  failure mode is a shared `tavolo.platform.errors` subclass.
+- `plugin.py` — `ScopaEngine` (two players) and `ScopaQuattroEngine`
+  (four players in fixed partnerships): the platform-facing adapters.
+  They translate create/join/websocket actions/deadlines into
+  rules-engine calls and back, validate the
+  `target_score`/`asso_pigliatutto` creation options (the match target
+  defaults to the traditional 11 points for two-player scopa and 21 for
+  scopa a quattro), and extract the `MatchResult` (teams, winner,
+  per-player scores and the match summary persisted as the match's JSON
+  `result`).
+
+Timeouts are constructor arguments (`turn_timeout_seconds`,
+`hand_ack_timeout_seconds`), wired from the environment by the
+application composition root.
+
+## Development (from `server/`)
+
+```sh
+uv run python -m unittest discover -s packages/tavolo-scopa/tests
+uv run mypy -p tavolo.scopa
+```
+
+`test_engine.py` covers the pure rules; `test_plugin.py` covers the
+platform contract (actions, deadlines, serialization, results).

+
+Rules implemented
+-----------------
+* 40-card Italian deck; three cards per player and four cards face up on
+  the table at the start of every hand; the rest of the deck stays out of
+  play until the next round of the hand.
+* When every hand is empty the dealer deals three more cards to each
+  player (no new table cards) and play resumes; this repeats until the
+  deck is exhausted. Two players play six rounds per hand, four players
+  three.
+* A card captures either a **single card of equal rank** or a **combination
+  of cards whose ranks sum to its own**. When an equal-ranked card is on the
+  table that capture is mandatory; the player may not take an alternative
+  combination instead. When any capture exists it must be taken.
+* Emptying the table with a capture is a **scopa** (+1), except on the very
+  last play of a hand — a sweep on the last play of a round still scores
+  when the deck has cards left.
+* At the end of a hand the remaining table cards go to the player who made
+  the last capture.
+* Hand points: ``carte`` (most captured cards), ``denara`` (most diamond
+  cards), ``settebello`` (the 7 of diamonds), ``primiera`` (best
+  seven/five/four/three card of each suit, all four suits required), plus
+  one point per ``scopa``. Ties on carte/denara/primiera award nothing.
+  With four players the partners' piles and scope are pooled.
+* Optional ``asso_pigliatutto`` rule (disabled by default; scopa d'assi):
+  an ace played when no equal rank is on the table sweeps the whole table
+  — or captures itself, leaving the table empty, when the table is bare.
+  The sweep never scores a scopa, even when cards remain in hand or in the
+  deck, but it counts as a capture for the last-taker rule. When another
+  ace is on the table the mandatory equal-rank capture still applies.
+* The match ends when a side reaches the target score with a clear lead; a
+  tie at or above the target is broken by playing another hand.

+means the store needs no custom codecs and the state is inspectable with

+The same state serves the classic two-player game and the four-player
+partnership variant (``player_count``): with two players the two seats

+and either way the side is the seat's parity. Within a hand the deck is
+dealt in rounds of three cards per player and persists across rounds in
+:attr:`ScopaState.deck`.

+The state contains only game data: the platform owns the session envelope
+(id, join code, seats, timestamps, stats persistence) — see
