- All install hooks now respect their respective XYZ_BINARY env vars
(e.g., WGET_BINARY, CHROME_BINARY, YTDLP_BINARY, etc.)
- Support both absolute paths (/usr/bin/wget2) and binary names (wget2)
- Dynamic bin_name used in Dependency JSONL output
- Updated 11 install hooks to follow the new pattern
- Mark checklist items as complete in TODO_hook_architecture.md
- Rename 13 on_Crawl__00_validate_* hooks to on_Crawl__00_install_*
- This better reflects what these hooks actually do (check/install binaries)
- Update TODO_hook_architecture.md to reflect renamed hooks
