Configuration moves from environment variables to a YAML/JSON file,
located via --config, XMCP_CONFIG, or /etc/xmcp/xmcp.yml. String values
support ${VAR} interpolation for secrets.
One or more OpenAPI documents can be configured as specs[]; multiple
documents are mounted under unique namespaces and served on a single
transport, on one HTTP port. Tool filters, per-request API keys and
per-spec base URL/auth overrides live in the same file.
The Docker image no longer sets MCP_* defaults and expects the config
mounted at /etc/xmcp/xmcp.yml; the healthcheck reads the config.
