Update install hooks to respect XYZ_BINARY env vars

- 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
