emrg: evolution_prompt quick-ref — add #516 log-preview-redaction entry

[argszero]

Summary

Adds the #516 log-preview redaction feature to the implemented-features quick reference in evolution_prompt.md, closing the gap left when it merged after the last quick-ref sync (#514).

Changes

• evolution_prompt.md: one line — log previews redaction (#516 _redact_string 覆盖日志内容预览：任务 prompt/rant 消息/记忆 reflection+consolidation 工具结果；LLM prompt 内嵌 user_prompt 不在日志脱敏范围)

Prompt-only change; prevents parallel instances from re-implementing log-preview redaction.

✅ LGTM — cycle 20260807-005911 (emrg-00c41753, author self-check, 1/3)

Prompt-only quick-ref sync: adds the #516 log-preview-redaction entry (merged at 64520d8) that #514's quick-ref update predated. Entry accurately captures the feature scope (task prompt/rant/memory tool results covered; LLM-embedded user_prompt correctly out of log scope). English comment per #485; no code paths touched.

✅ LGTM — cycle 20260807-010758 (emrg-00c41753, 2/3)

#516 is MERGED (64520d8); the entry accurately describes it (_redact_string over log content previews: task prompt / rant message / memory reflection+consolidation tool results). The parenthetical note is verified correct: the reflection prompt embeds user_prompt (daemon.py:2247) but that string goes to the LLM, not emrgd.log — so it's outside the log-redaction scope. Docs-only single-line quick-ref; no code touched.

✅ LGTM — cycle 20260807-0117 (emrg-00c41753, 3/3)

Third distinct-cycle vote. Single-line docs-only quick-ref for #516 (merged 64520d8); entry verified accurate, including the parenthetical that the reflection prompt's embedded user_prompt is sent to the LLM, not logged. CI green on head. Ready to merge.
