* 🛑 fix: Confirm Scheduled Stops and Separate Terminal Scheduler Failure from Startup

Fixes #15042, fixes #15043.

`resume.js` inferred a confirmed stop from the ABSENCE of `failureReason`, but
`abortJob` had four `success: false` paths that returned no reason at all. Those
settled the occurrence as `interrupted` and pruned the checkpoint on aborts that
never landed — including one where a REPLACEMENT generation owned the
conversation, which pruned the successor's checkpoint.

Every `success: false` return now names itself (`job_not_found`,
`already_settled` added alongside the existing `generation_replaced` /
`job_still_active`), and a single canonical `isStopConfirmed` predicate decides
whether durable state may be settled. `already_settled` confirms a stop —
`awaitProviderDrain` has proven the provider segment can no longer persist — so a
permanently terminal generation is not answered with a retry loop.

Separately, a schedule engine that failed to arm advertised its permanent outage
as a transient 503 with `Retry-After`, so a client obeying it would poll forever.
Readiness is now tri-state (`starting` / `armed` / `unavailable`): the retry
contract applies only while arming is genuinely pending, and a failed arm returns
a terminal `SCHEDULES_UNAVAILABLE` with no `Retry-After` and an error-level log.

* 🏷️ fix: Declare Schedule Write Gate Return Types

`--isolatedDeclarations` requires an explicit return type on the exported factory
and on the middleware it returns (TS9007). Adds a named `ScheduleWriteGate` type
matching the existing `ShareMiddleware` shape.
