/**
 * Structured daemon logging, now backed by `@danypops/vehicle-server/logging` (pino) instead of a
 * hand-rolled `console.error(JSON.stringify(...))` -- gains real level filtering (including a real
 * debug level this daemon previously had no way to emit at all) and a destination injectable for
 * tests, matching jittor/src/log.ts's already-migrated shape exactly. One deliberate, disclosed
 * shape change from the old bespoke format: the event name is now pino's `msg` field rather than a
 * separate `event` field, matching daemon-kit's shared convention across every migrated daemon.
 * `component`/`level`/`timestamp` and credential-safety (callers still must pass only bounded,
 * non-sensitive fields; @danypops/vehicle-server/logging's own default redact list also catches any
 * credential-shaped field that slips in regardless) are unchanged.

 * Also satisfies @danypops/vehicle-server's own `Logger` port directly wherever one is needed (e.g.
 * `createVehicleHttpApp`'s failure logging in daemon.ts), replacing the old `vehicleLogger()`
 * adapter now that this logger already natively implements the full debug/info/warn/error surface.
