Add README.md generation to status command
The status command now automatically generates and commits a README.md
file in the main worktree with workspace status in markdown format:
- Summary table with project/package/repo counts
- Projects table with merge counts and status indicators
- Opam packages table with patch counts and merge info
- Git repositories table
- Active worktrees section
Added --no-readme flag to skip README generation.
Added str library dependency for content comparison.
