OrcaWinandOrcaWin fb3a3c5643 perf(native-chat): probe WSL transcript paths asynchronously (#13265)
* perf(native-chat): probe WSL transcript paths asynchronously

The WSL transcript resolvers probed `\wsl.localhost` UNC candidates with
existsSync. Those paths are served over 9P, so a stopped or unreachable distro
blocked the Electron main thread instead of falling through to the next
candidate.

- host-readable-transcript-path: the `pathExists` dep is now async, defaulting
  to fs/promises.access. The per-distro loop stays sequential — the ranked order
  exists so the owning distro wins, and probing every distro at once would fan
  9P calls out to ones the user deliberately left stopped.
- session-file-resolver: dropped the existsSync guard outright rather than
  converting it. walkSessionFiles already yields [] for a missing or unreadable
  root, so the guard was redundant as well as blocking.

* perf(native-chat): stop the resolve poll mkdir-ing the Codex runtime home

codexSessionsDirs() only needs the managed home's path to scan it, but called
getOrcaManagedCodexHomePath(), which mkdirSyncs. That put a synchronous fs call
back on the 500ms-5s resolve poll the surrounding async probe work just cleared,
and materialized the runtime home as a side effect of a read-only lookup.

Use the resolve-only variant the module already exposes for this case. A missing
root walks to no matches, so behavior is unchanged.

* perf(native-chat): gate WSL transcript fs access behind a shared queue

Serializes and dedupes WSL 9P filesystem probes (access/readdir) so a
stopped or slow distro can't exhaust the shared libuv threadpool or
block unrelated local filesystem work. Routes Codex session-tree scans
and path-existence checks through the new wsl-transcript-fs-gate,
while sharing in-flight scans across concurrent callers.

* perf(native-chat): prioritize exact WSL transcript probes over scans

- Add cancellation (AbortSignal) throughout session resolution and
  directory walking so an unsubscribed transcript watch stops
  in-flight WSL filesystem work instead of leaking it.
- Split the WSL fs task gate into exact vs scan priority lanes with
  per-route concurrency, so a live transcript access probe is never
  queued behind a directory scan on another distro/provider.
- Extract Codex WSL session path scanning into its own module that
  shares one root snapshot across concurrent session-id lookups and
  refreshes on a shared miss to see post-start file creation.
- Skip the async WSL probe entirely for local paths via existsSync.

* fix(native-chat): harden WSL transcript cancellation

* fix(native-chat): finish transcript cancellation
