Continued and added one final signoff artifact:

- [samples2tools_completion_report.txt](C:\Users\davidq\Documents\GitHub\HTML-JavaScript-Gaming\docs\dev\reports\samples2tools_completion_report.txt)

It summarizes:
- roadmap completion (`0` non-legend unchecked items),
- current samples/tool mapping totals (`53` rows across `16` tools),
- full Phase 20 removal confirmation,
- games lane coverage (`11` launchable, `0` boot wiring issues),
- references to the key final validation reports.

Commit comment:
`Add final Samples2Tools completion report consolidating roadmap status, mapping counts, phase-20 removal confirmation, games workspace wiring coverage, and key validation report references.`
