Bug: peek scan doesn't respect nested .gitignore files in subdirectories

[hariomlohardev]

Description

Dogfooding bug — scanner.py loads .gitignore only at root via pathspec, but nested .gitignore in src/foo/.gitignore is ignored. git check-ignore would respect it.

Files

• peek/peek/scanner.py — _load_ignore_spec should walk subdirectories
• peek/tests/test_scanner.py — add test_nested_gitignore

Acceptance

• src/foo/.gitignore with *.pyc is respected when scanning src/foo/bar.py
• pytest -q passes

Time

~45 min — real bug, great for first PR that touches scanner
