A versioned control-plane REST API (/api/v1) on its own port (default
127.0.0.1:47990) serving host info, runtime status, paired-client
management, the pairing PIN flow, and session control (stop / force-IDR).
The OpenAPI 3.1 document is generated from the handlers by utoipa, served
live at /api/v1/openapi.json (+ Scalar docs at /api/docs), printable via
`lumen-host openapi`, and checked in at docs/api/openapi.json for client
codegen — a test fails if it drifts, mirroring the cbindgen header rule.
Auth: optional bearer token (--mgmt-token / LUMEN_MGMT_TOKEN), enforced on
everything but /health, and mandatory for non-loopback binds. PinGate
gains a waiter count so the API can report pin_pending; logs moved to
stderr so stdout stays machine-readable. Supersedes the web.rs stub.
