feat: implement phase 1 sync functionality

- Add lnk status command to show repository sync status

- Add lnk push command for smart staging, committing, and pushing

- Add lnk pull command with automatic symlink restoration

- Add comprehensive sync functionality to git and core packages

- Add 5 new integration tests for sync commands (17 total tests)

- Update README with sync workflow examples and documentation

- Support commits ahead/behind tracking relative to remote

- Implement change detection to avoid empty commits

- Add graceful error handling for missing remotes

Closes: Phase 1 sync implementation
