v0.24.4

Chores

• refactor: extract cowork session key helpers into cowork-session.ts (#544, closes #499)

Notes

orchestrator.ts is 1696 lines — the issue asked for a full split. The naive barrel approach breaks the test suite's module-isolation pattern (t.mock.module() + ?case=URL trick): sub-modules get Node-cached after the first test load, stale mock refs propagate silently, and the test runner hangs. The pure cowork helpers (CoworkSessionError, isCoworkSessionKey, coworkSessionIdFromSessionKey) have no mocked imports and no module-level closures, so they're the one safe extraction. A full decomposition would require either refactoring the test pattern or switching to dependency injection throughout orchestrator — tracked for a future sprint.
