Jinwoo Hong b06f40f3ba fix(opencode): read the binder's session store off the main thread; ship the reader worker in orcad (#24638)
* fix(opencode): read the binder's session store on the foreign SQLite reader worker (STA-9122)

Before: the OpenCode session binder listed new sessions from opencode.db with
node:sqlite on the main thread every 60 s (and on SessionStart kicks), so a
large or contended store could stall the app the same way Cursor's did.

After: the read is a pure openCodeBinderSessions reader in
foreign-sqlite-readers/readers/, run only on the worker. The binder's
correlation, pane snapshot and process sweep stay where they were.

- The binder round awaits listSessions and re-checks its generation right
  after, so a stop() during the read discards the round before it touches the
  unbound map or the watermark.
- The client's in-flight dedupe key now includes the cursor, so a stale round
  from before a restart cannot hand its rows to the restarted round.
- Idle teardown is per reader. The binder lane keeps its thread for 120 s,
  longer than its 60 s poll, so the thread is not respawned every round.
- A timeout, crash, malformed reply or unstartable worker resolves to [] (no
  sessions), the value the old read already returned on failure.
- An absent store still reads as [] without a log line, and a permission or
  corrupt-file failure still logs (kept from #24577, now in the reader: it
  stats the path and throws anything but ENOENT/ENOTDIR to the client's log).
- The binder lane inherits #24572's limits from the shared lane: no respawn
  until a timed-out worker has exited, 2 consecutive deaths, a queue cap of
  8. Its timeout stays 60 s, matching its poll.
- dispatch switches on the destructured kind, so a new kind without a case
  still fails to compile.

orcad: the hook server runs there too, so orcad now ships
foreign-sqlite-reader-entry.js beside orcad.js (ORCAD_ARTIFACTS, built as an
orcad child). build-orcad runs a smoke check that starts the built worker
under the build's Node and under the pinned runtime, and does a real binder
read on a fixture DB, a Cursor read of a missing file and an OpenCode history
list. The OpenCode history scanner uses the same entry and was bundled into
orcad without it, so on orcad it always failed closed; it can now run.

Tests: reader (cursor, same-ms ids, OpenCode 2 rows, missing then created,
corrupt, inaccessible directory), retirement gate for the binder lane, dispatch
routing, client lane (rows, failure -> [], dedupe per cursor, own thread, idle
teardown default and override), binder loop with an async listSessions
(failure -> [], stop during the read), orcad path resolution through orcad's
host adapters, artifact list, and the smoke check against good, missing and
non-reading entries.

* test(opencode): cover the binder read deadline with fake timers and name the failure test accurately (STA-9122)
