Bug: Symlinks in scanned directory cause infinite loop / double-counting

[hariomlohardev]

Description

Dogfooding — worth actually testing before filing. scan() follows symlinks via Path.resolve() in path_to_file but rglob may follow symlink loops.

Files

• peek/peek/scanner.py — add is_symlink check + visited inodes
• peek/tests/test_scanner.py — add test_symlink_loop

Acceptance

• tmp/repo/a.py -> b.py symlink loop doesn’t hang or double-count
• pytest -q passes
