Pull request overview

This PR updates workspace autosave so local workspace names are preserved from persisted state when the PR title input is empty, which fits the app’s IndexedDB-backed workspace restore/autosave flow.

Changes:

• Extend createWorkspaceContextSnapshotGetter to use persisted local workspace titles as a fallback.
• Wire app.js state into the snapshot getter so it can read workspace scope and the active persisted title.
• Add a Playwright regression test covering rename persistence after an editor change.
