Keep calls and hand acts on the bus, answer status at once, record durations (hq to-be 45 Phase 0)

A controller restart lost every call's outcome, `status` composed the mesh
while its caller waited (18.6s live on 2026-10-06, past the 10s window), a
repair by hand left no trace, and the core's bounds had nothing measured to
be set from.

- calls: kept in the controller's bucket mesh-controller_calls (last 1000 or
  14 days, answers bounded to 64 KiB), read by id across a restart; a
  controller starting marks a stopped one's running calls abandoned; each
  call names its caller from the inbox its answer goes to.
- status: the serving controller composes it at start, after news from a
  machine, a build or an acting verb, and every minute; the verb answers the
  last composition at once with when and how long it took. Composing resolves
  each machine once instead of twice.
- hand-act log in mesh-controller_hand-acts: push (required through the seat),
  plans stop/close, broker consumer-reset and the new hand-act record take
  --why/--cause/--condition; `hand-acts` lists them and repeated causes;
  status counts the week's.
- durations (migration 0066): apply (send to first report), heartbeat gap,
  plan tier and build, recorded as heard; `durations` summarises them.
- the controller's seat row takes this binary's definition of its own verbs,
  so the console no longer judges calls against an older build's schema.
- the controller is granted its two buckets' subjects.
