Use G3Status formatting for /project loading message

Changed from 'Project loaded: ✓ file1  ✓ file2' to
'g3: loading <project-name> .. ✓ file1  ✓ file2 .. [done]'

- Add G3Status::loading_project() for consistent status formatting
- Update /project command to use new formatting
- Remove unused crossterm imports from commands.rs
