Implemented AR thin archive support with external file references.

Features added:

  1. Thin archive writer (--thin flag) that writes external file references for regular files (data stored as path to original file) while still storing symlink targets inline.

  2. Format detection: FormatARThin registered separately; reader auto‑detects thin magic !<thin>\n.

  3. CLI integration: reptar -c --format ar --thin creates thin archives; reptar -t -f archive.thin lists them correctly.

  4. BSD long filename handling and directory entries fixed (see #196).

  5. Metadata handling respects --no‑internal‑meta flag.

All unit tests pass, including new tests for BSD long filenames and directory entries in thin archives.

This completes AR thin archive support as part of Phase 7.
