The format ran mkfs under the HTTP request context, so the controller's 15s client
timeout cancelled it → SIGKILL mid-write → corrupt disk. Now mkfs runs DETACHED off
s.baseCtx (a dropped request can't kill it) via a persisted formatJob record; the handler
still waits to return the synchronous result (backward-compatible with the v0.62.0
controller) but abandoning the wait on client-disconnect leaves the mkfs running to
completion. New GET /disks/format/status surfaces the job (additive). RecoverFormatJob
runs on agent startup: a record left 'running' (agent died mid-format) is re-resolved by
durable-id (anti-retarget — absent/swapped disk NOT re-formatted) and the mkfs re-run; a
blank/path-bound interrupted format is marked failed (retry), never auto-re-run.
Tests: detached run persists running→done + binds durable-id; status endpoint; recovery
re-runs an interrupted durable-id-bound format; skips blank; skips unresolvable durable-id.
