refactor: simplify brew.sh with native macOS tools
- resolve_path: use realpath (macOS 12.3+) instead of python3/perl - deduplicate tokens with sort -u instead of manual loop - reuse _extract_cask_token_from_path in symlink check - simplify brew_uninstall_cask boolean logic Reduces 88 lines (281 → 193)
