emrg: evolution_prompt quick-ref for #688/#689/#690 (icon finalization + stop-emrg fix + gen-assets doc)

[argszero]

Adds implemented-features quick-reference entries to emrg/server/evolution_prompt.md for the three PRs merged since the last quick-ref (#686):

• emrg: app icon finalization — Branch Emergence SVG design source + gen-assets pipeline (rant 2026-08-11T18:28:09) #688 — App icon finalization: reconstructed packaging/assets/icon.svg from the rant's design spec (the embedded SVG source was a literal %s placeholder), new gen-assets.sh SVG→PNG pipeline + CI icon-asset step, 5 binary products gitignored
• emrg: stop-emrg.cmd — kill only EMRG-owned git trees, never host Git Bash sh/vim (rant 2026-08-11T18:56:58) #689 — stop-emrg EMRG-tree-only kill (rant 2026-08-11T18:56:58): fixes emrg: Windows installer — kill orphaned bundled-git processes before overwrite (rant 2026-08-11T17:56:25) #683's blanket path-prefix kill that also killed the host's Git Bash sh/vim; final design snapshots the EMRG tree downward before any kill (dead-daemon orphans still captured) — the ancestor-walk variant was rejected in review because it cannot resolve dead parents
• emrg: document gen-assets.sh for local packaging (post-#688 host symmetry) #690 — Packaging doc (Agent.md + DEVELOPMENT.md): local installer builds must run gen-assets.sh first (icon products gitignored; emrg: p12 双证书对称校验 — Application + Installer 缺一不可（防止只导 Installer 导致 .app 未签名） #467/emrg: docs — README 补充 p12 双证书本地验证命令 + CI 早检行为说明（#467 对称） #468 host symmetry)

Also updates the #683 entry's trailing note ("修正 PR 待合并" → "修正 #689 已合并 888efb0").

No test/doc-count changes (quick-ref entries are exempt from doc-count guard per established pattern). Local: pytest 694 ✓ import ✓ --help ✓.

✅ LGTM — cycle (1st)

Quick-ref entries for #688/#689/#690 added to evolution_prompt.md, plus the #683 entry's trailing note updated ("修正 PR 待合并" → "修正 #689 已合并 888efb0"). Verified against the merged commits:

• #688 entry accurately captures the icon SVG reconstruction (literal %s placeholder → rebuilt from design spec), gen-assets pipeline, and the two review fixes (cygpath file-URL, iconutil macOS guard)
• #689 entry records the full lesson chain: path-prefix blanket kill → ancestor-walk (rejected: dead parents) → snapshot-downward final design
• #690 entry documents the Packaging host-symmetry docs

Doc-only change; no test/doc-count impact. Local pytest 694 ✓ import ✓ --help ✓; CI Test PASS (31485794247).

✅ LGTM — cycle (1st)

Quick-ref entries for #688/#689/#690 verified against git history:

• #688 merge commit afbfaea ✓ (icon.svg reconstruction, gen-assets pipeline, cygpath + iconutil fixes)
• #689 merge commit 888efb0 ✓ (step-0 downward BFS snapshot — captures the R827 ❌ → e67e604 fix evolution accurately)
• #690 merge commit 6b8fff3 ✓ (gen-assets doc, host symmetry)
• #683 entry updated with 修正 #689 已合并 888efb0 — consistent
  Format matches the quick-ref convention (rant timestamps, design details, merge commits). CI Test green (31485794247). Mergeable.

✅ LGTM — cycle (3rd)

Re-verified on head 400ad7b (unchanged since 1st/2nd LGTMs):

• Quick-ref entries for #688 (icon SVG reconstruction + gen-assets pipeline), #689 (snapshot-downward EMRG-tree-only kill with the dead-parent review lesson), #690 (Packaging doc) — all consistent with merged commits afbfaea/888efb0/6b8fff3
• #683 entry note updated ("修正 PR 待合并" → "修正 #689 已合并 888efb0")
• Doc-only change; local pytest 694 ✓ import ✓ --help ✓; CI Test PASS (31485794247)

Mergeable.
