[codex] Fix workspace switch crash

[samuelstroschein]

Summary

Fixes workspace switching so Flashtype closes the current Lix session before adopting the next workspace.

The crash/stale-state path came from updating the main-process workspace descriptor before tearing down the old Lix handle. That could leave the window showing the new workspace while data was still served from the previous one, especially when switching into an empty folder.

Changes

• Serialize main-process workspace changes so overlapping workspace.open calls cannot race.
• Close the current Lix session before changing workspaces, while allowing workspace switching to recover from a failed old Lix open.
• Add an Electron e2e regression for switching from a populated workspace into an empty folder.
• Add a patch changenote.

Validation

• pnpm exec oxlint --tsconfig ./tsconfig.json --format stylish electron/main.mjs electron/ipc-lix.mjs electron/lix.mjs electron/workspace.mjs e2e/workspace-switch.spec.ts
• pnpm run typecheck
• pnpm exec playwright test e2e/workspace-switch.spec.ts
• node scripts/validate-changes.mjs

Note

Medium Risk
Touches main-process workspace and Lix lifecycle ordering; behavior change on every folder switch, though scoped and covered by a new e2e test.

Overview
Fixes crashes and stale UI when switching workspaces (especially into an empty folder) by tearing down the current Lix session before the main process adopts the next workspace path.

Workspace opens are serialized via a queue so overlapping workspace.open calls cannot race. registerWorkspaceIpc now accepts a beforeChange hook; startup wires it to closeLixSession({ ignoreOpenError: true }) so a failed old Lix open does not block switching. Lix teardown is centralized in closeLixSession (IPC handles, transactions/observers, then closeLix with optional ignoreOpenError).

Adds an Electron e2e regression (populated folder → empty folder) and a patch changenote.

Don't ignore old-session close failures

In the workspace-switch path this passes ignoreOpenError into closeLixSession, but closeCurrentLix applies that flag to the whole try, including await lix.close(). If the previous workspace opened successfully but its native close/flush fails, the switch still advances to the new workspace and clears lixPromise, leaving the old session unclosed—the stale-handle state this change is meant to avoid. Please only ignore rejection from the old open promise, not failures from closing an already-open session.
