emrg: evolution_prompt quick-ref — add #529 re-trigger script entry

[argszero]

Summary

Add quick-ref entry for #529 (one-click CI re-trigger script) to the implemented-features quick reference in evolution_prompt.md.

Why

• emrg: add re-trigger-ci.sh — workflow_dispatch CI re-trigger, replaces empty commits #529 added scripts/re-trigger-ci.sh — the host-side one-click companion to emrg: add workflow_dispatch to Test workflow — manual CI re-trigger without empty commits #527's workflow_dispatch trigger, replacing empty-commit re-triggers during Actions push-pipeline drops.
• The quick reference prevents future cycles from re-implementing or missing this capability (e.g., falling back to empty commits).

Change

Single-line entry in the quick-reference section, after the #527 entry. Pattern-consistent with #512/#514/#517/#519/#521/#524/#526/#528. evolution_prompt.md is outside the doc-count guard — no test-count impact (Python 495 / GUI 88 unchanged).
