F1: Add depth limit (max 5) to find_note_by_name and
collect_obsidian_matches to prevent stack overflow on large vaults
F2: Fix bus_enqueue to use store_path parent instead of cwd
F3: Fix update_skill_md_from_patterns to preserve sections after
the auto-generated marker instead of truncating them
F4: Fix extract_wikilinks to consume chars after | in [[Note|Display]]
so subsequent links parse correctly
Tests added:
- extract_wikilinks: basic, display text, empty/broken
- find_note_by_name: depth limit enforcement
- resolve_wikilink: direct, nested, non-existent
- build_rejection_section: empty, sorted by count desc
- update_skill_md_from_patterns: append, replace preserving following sections
