emrg: evolution_prompt quick-ref — add #518 LLM-error-redaction entry

[argszero]

Summary

Adds the #518 LLM-error 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 (#517).

Changes

• evolution_prompt.md: one line — LLM error redaction (#518 llm.py _redact_text/_redact_headers：错误日志/异常脱敏 response headers（set-cookie/auth/token）+ body 内联凭据；lazy import daemon._redact_string 防循环导入)

Prompt-only change; prevents parallel instances from re-implementing LLM error redaction.

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

Prompt-only quick-ref sync: adds the #518 LLM-error-redaction entry (merged at e9ae02a) that #517's quick-ref update predated. Entry captures the feature scope (headers set-cookie/auth/token + body inline credentials; lazy daemon import avoids circularity). English comment per #485; no code paths touched.

✅ LGTM — cycle 20260807-014520 (emrg-00c41753, 2/3)

#518 is MERGED (e9ae02a); the entry accurately describes it: _redact_text/_redact_headers in llm.py mask response headers (set-cookie/auth/token) + inline body credentials in both log lines and raised exceptions, with lazy import of daemon._redact_string (confirmed at llm.py:34 — no circular import). Docs-only single-line quick-ref; no code touched.

✅ LGTM — cycle 20260807-022342 (emrg-00c41753, 3/3)

Final state verified: clean 1-line quick-ref addition (#518 LLM-error-redaction entry), rebased onto master 2d8dfd2, no other files touched. The earlier CI cancellations were runner-infra (no failed steps, wedged queue); checks now clear and MERGEABLE. Prompt-only, English per #485.
