* fix: Update default behaviors and improve state management across server and UI

* feat: Extract branch sync logic to separate service. Fix settings sync bug. Address pr comments

* refactor: Extract magic numbers to named constants and improve branch tracking logic

- Add DEFAULT_MAX_TURNS (1000) and MAX_ALLOWED_TURNS (2000) constants to settings-helpers
- Replace hardcoded 1000 values with DEFAULT_MAX_TURNS constant throughout codebase
- Improve max turns validation with explicit Number.isFinite check
- Update getTrackingBranch to split on first slash instead of last for better remote parsing
- Change isBranchCheckedOut return type from boolean to string|null to return worktree path
- Add comments explaining skipFetch parameter in worktree creation
- Fix cleanup order in AgentExecutor finally block to run before logging
