emrg: evolution_prompt quick-ref — add #527 workflow_dispatch entry

[argszero]

Summary

Add quick-ref entry for #527 (Test workflow workflow_dispatch trigger) to the implemented-features quick reference in evolution_prompt.md.

Why

• emrg: add workflow_dispatch to Test workflow — manual CI re-trigger without empty commits #527 added workflow_dispatch: to .github/workflows/test.yml, enabling manual CI re-trigger via gh workflow run test.yml --ref <branch> when the push-event pipeline drops runs (as during tonight's Actions outage).
• The quick reference prevents future cycles from re-implementing or missing this capability (e.g., falling back to empty-commit re-triggers, which pollute git history and fail when the push pipeline is down).

Change

Single-line entry in the quick-reference section, after the #525 entry. Pattern-consistent with #512/#514/#517/#519/#521/#524/#526. evolution_prompt.md is outside the doc-count guard — no test-count impact (Python 495 / GUI 88 unchanged).
