Update logging levels in Rojo plugin and enhance test plans

- Promoted sync-related logging from Debug/Trace to Info level across multiple files, ensuring visibility of changes in the Studio output console.
- Added a new plan for expanding the connected mode test suite to cover multi-step scenarios and round-trip identity verification.
- Introduced a plan to fix stale tree desynchronization by implementing a validation mechanism on plugin connection.
- Created a plan to bump sync logging to Info level, detailing todos for various components in the plugin.

This update improves the clarity of logs and enhances testing coverage for connected mode scenarios.
