Add CI pipeline documentation and enhance syncback architecture

- Introduced a new CI pipeline documentation file outlining steps for auto-fixing formatting, running linters, building, and testing.
- Documented the Rojo syncback architecture, detailing improvements to prevent duplicate file creation and format mismatches.
- Updated syncback logic to ensure existing instances are updated instead of creating duplicates, enhancing project file management.
- Added tests for encoding instances and handling nested children to improve reliability in syncback operations.
