What does this PR do?

Projects and home sessions could become out of sync when the same OpenCode data was accessed from multiple browsers or server contexts.

This PR:

• Notifies the app when projects are loaded or updated so they can be discovered in the active browser.
• Discovers project directories referenced by Home sessions.
• Loads late-discovered project sessions through a deduplicated sequential queue.
• Normalizes worktree paths when opening, closing, removing, expanding, collapsing, moving, or discovering projects.
• Persists dismissed projects so a user-closed project is not automatically reopened by background discovery.
• Migrates legacy recentlyClosed and non-local server state into the canonical local state.
• Adds handling for global project update events.
• Disables the channel database for the Desktop server.
• Adds regression tests covering cross-browser project updates, session discovery, path normalization, migration, dismissal persistence, and queued session loading.

These changes keep project and session state consistent across browser instances while preserving explicit user actions such as closing or reopening a project.

How did you verify your code works?

Added and updated Bun tests covering:

• Global project bootstrap and project update events.
• Home session directory discovery.
• Sequential and deduplicated project session loading.
• Normalized worktree paths.
• Project dismissal and rediscovery behavior.
• Legacy state migration.

The full test suite should be run locally before submitting the PR.

Not applicable. This PR changes synchronization and state management behavior without introducing a new UI.

  • fix(app): defer background workspace discovery #47428
  • This PR addresses background workspace discovery, which is closely related to the project discovery and session sync functionality in PR fix(app): restore project and session sync across browsers #48143. Both PRs deal with discovering and managing projects in the background.

The current PR (48143) is comprehensive in addressing project and session synchronization across browsers. The searches confirm no other duplicate PRs exist that address the same cross-browser sync issue, path normalization, or dismissal persistence features.
