Updates the doc to reflect the 2 follow-on improvements to
collision detection:
- Phase 5.1 added 'recipe files' source (handles the 39 recipes
with [[package]].files dict). Out-of-scope #1 in this doc
marked as DONE.
- Phase 5.4 added --selftest mode with 8 regression cases wired
into the pre-push hook. Future-work item #4 added for property-
based fuzzing (e.g. hypothesis).
