feat(mcplocal+mcpd): wake-recipe config + wake-task execution (v2 Stage 1)

First half of v2 — mcplocal can now declare a hibernating backend and
respond to a `wake` task by running a configured recipe. v2 Stage 2
will wire mcpd to dispatch the wake task before relaying inference.

Config (LlmProviderFileEntry):
- New \`wake\` block on a published provider:
    wake:
      type: http        # or: command
      url: ...           # http only
      method: POST       # http only, default POST
      headers: {...}     # http only
      body: ...          # http only
      command: ...       # command only
      args: [...]        # command only
      maxWaitSeconds: 60 # how long to poll isAvailable() after wake fires

Registrar (mcplocal):
- At publish time, providers with a wake recipe whose isAvailable()
  returns false report initialStatus=hibernating to mcpd. Without a
  wake recipe (legacy v1) or when already up, status stays active.
- handleWakeTask: runs the recipe (HTTP request OR child-process
  spawn), then polls isAvailable() up to maxWaitSeconds, sending a
  heartbeat each loop so mcpd's GC sweep doesn't time us out
  mid-boot. Reports { ok, ms } on success or { error } on
  timeout/recipe failure via the existing _provider-task/:id/result.
- Replaces the v1 stub that rejected wake tasks with "not implemented".

mcpd VirtualLlmService:
- RegisterProviderInput gains optional initialStatus ('active' |
  'hibernating'). The register/upsert path uses it for both new and
  reconnecting rows. Defaults to 'active' so v1 publishers still
  work unchanged.
- Provider-register route's coercer accepts the new field.

Tests: 3 new in registrar.test.ts cover initialStatus selection
(hibernating when wake configured + unavailable, active otherwise,
active when no wake even if unavailable). 8/8 registrar tests, 833/833
mcpd unchanged.
