chore: HOME-relative paths, untrack scratch/, refresh CLAUDE.md

The menu scripts and cursor.rs context-menu spawns resolve ~/.local/bin
through HOME instead of a hardcoded /home/lsgalante. scratch/ debug
artifacts leave version control (files stay on disk, now gitignored).
CLAUDE.md drops its stale-README note (README was already rewritten)
and the TOML-comments note (those comments are gone), and updates the
central-file descriptions for the policy-crate split.
