v0.10.0

Added

• commit command — commit specific hunks directly without manual staging (git hunk commit <sha>... -m "message")
  • Uses save/restore index approach so pre-commit, commit-msg, and post-commit hooks run normally
  • Existing staged changes are preserved — only specified hunks are committed
  • --all to commit all unstaged hunks, --file to commit hunks in a specific file
  • --amend to amend the previous commit with additional hunks
  • --dry-run to preview what would be committed
  • --ref <refspec> to commit hunks from a ref-based diff
  • Line specs supported (e.g., sha:3-5,8) for partial-hunk commits
  • Crash recovery: detects and restores stale index backups from interrupted commits
  • 16 integration tests covering basic usage, hooks, crash recovery, and edge cases
