Neil 3b67c2acb5 fix(main): move freeze-prone sync fs off the main thread
A synchronous fs syscall on the Electron main thread parks the whole app
when its target is on a stalled mount (SMB/NFS, VPN drop, sleeping NAS,
unmounted drive). The app stops repainting and stops answering Force Quit.
This converts 28 such paths, covering the ones users actually hit:

- orca.yaml hook config, read behind the POLLED git:status path, so a
  stalled repo froze the app on a timer with no user action
- agent hook status/install for 14 agents, incl. the shared reader that
  10 of them funnel through and a serial install loop with sync fs per body
- credential status for Codex/Grok/MiniMax/speech, also called off-IPC by
  RateLimitService on a refresh timer -- froze a fully idle app
- external path authorization and agent trust setup
- profile index, keybindings, diagnostics discovery

Measured first, since it shapes the fix: libuv's threadpool defaults to 4
threads, and at exactly poolSize concurrent stalled ops every other async
fs call app-wide stops progressing. But the event loop stayed alive in all
configurations (max timer gap 4ms). So async conversion does not bound a
hung mount -- it keeps the main thread responsive, which is the reported
symptom. UV_THREADPOOL_SIZE is raised to 16 as headroom, not as a bound.
No timeout machinery was added; it cannot bound a block on its own thread.

Where a sync twin had to stay (CLI processes, pre-window startup, callers
that cannot await), the write path keeps single-thread serialization rather
than relying on a promise chain a sync writer walks straight through:
canonicalization moves off-thread while the read-modify-write stays sync.
Where both twins must coexist, the async writer publishes its temp path and
the sync writer unlinks it, turning the parked rename into a swallowed
ENOENT -- a generation guard alone is spent once the writer parks.

observability/local-file-sink.ts is deliberately untouched; its writeSync
is a crash-durability contract that needs a process boundary, not an await.
