…ups (openclaw#67687)

Feishu config defaults groupPolicy to 'allowlist'. Inbound group handling read groupAllowFrom and called isFeishuGroupAllowed before resolveFeishuReplyPolicy was reached, so a config that only set channels.feishu.groups.<chat_id>.requireMention=false (with no groupAllowFrom) was rejected with 'group not in groupAllowFrom' before per-group requireMention could take effect. Treat the explicit presence of a group entry under channels.feishu.groups as the operator's allowlist signal: if groupConfig is defined, skip the empty-allowlist rejection. resolveFeishuReplyPolicy still owns mention gating, and existing groupConfig.enabled=false / groupAllowFrom-driven rejections are preserved. Adds a regression test that exercises the reporter's exact config shape and confirms inbound text reaches finalize/dispatch.

Add a manual macOS CodeQL security shard scoped to app sources. Verified with profile=macos-security on Blacksmith in 16m55s.

Remediate current-profile CodeQL findings for file SecretRef id validation and release workflow job permissions. Includes changelog credit. Thanks @vincentkoc.

…Message voice-memo bubbles via BlueBubbles (openclaw#72586)

End-to-end testing on macOS + BlueBubbles + ElevenLabs walked through three CAF flavors before landing on the format Apple's Messages.app actually emits when a user records a native iMessage voice memo:

- PCM int16 @ 44.1 kHz CAF: BlueBubbles' internal `afconvert -f m4af -d aac` conversion fails; the original CAF reaches iMessage but renders with 0 s duration.
- AAC @ 22.05 kHz mono CAF: BlueBubbles' conversion succeeds and the server silently downgrades the delivery, sending the converted MP3 as a generic audio attachment.
- **Opus @ 24 kHz mono CAF**: byte-identical to the descriptor block Apple's Messages.app produces; BlueBubbles passes it through unchanged and iMessage renders a native voice-memo bubble with proper duration and waveform UI.

Adds an opt-in `tts.voice.preferAudioFileFormat` channel capability and a macOS `afconvert`-backed pre-transcode in the speech-core pipeline. BlueBubbles declares `preferAudioFileFormat: "caf"`. Other channels are unaffected. Falls back to the original buffer when the host platform, the source/target pair, or the transcoder process can't produce the preferred container — so non-Darwin hosts and unsupported provider combinations are unchanged.

Also adds a `caff` magic-byte sniff in `src/media/mime.ts` so the auto-reply host-local-media validator (which uses `file-type` and didn't recognize CAF natively) accepts the buffer instead of dropping it as "⚠️ Media failed."

Fixes openclaw#72506.
