- Export `directoryExists` in `utils` to safely validate working directories before traversal.
- Update `SessionManager` and startup logic to fallback to the launch directory if a session's recorded working directory no longer exists.
- Add regression tests to ensure sessions now correctly adopt the launch directory instead of crashing on missing paths.
- Add `directoryExists` check to validate session working directories.
- Skip updating the session cwd if the recorded directory no longer exists on disk to prevent runtime errors.
Skip the secondary loadSystemPromptFiles capability walk when the caller already controls block 0 via customPrompt/resolvedCustomPrompt, so project/user SYSTEM.md cannot silently augment a CLI --system-prompt override.
Fixes#3014

- Added comprehensive unit tests in `settings-manager.test.ts` to verify backward-compatible migration behavior.
