test(active-memory): clean threaded DM coverage

CHANGELOG.md

@@ -1919,7 +1919,6 @@ Docs: https://docs.openclaw.ai
 - Gateway/sessions: stream bounded transcript reads for session detail, history, artifacts, compaction, and send/subscribe sequence paths so small Gateway requests no longer materialize large transcripts or OOM on oversized session logs. Thanks @vincentkoc.
 - Gateway/chat: bound chat-history transcript reads to the requested display window so large session logs no longer OOM the Gateway when clients ask for a small history page. Thanks @vincentkoc.
 - BlueBubbles: detect audio attachments by Apple UTIs (`public.audio`, `public.mpeg-4-audio`, `com.apple.m4a-audio`, `com.apple.coreaudio-format`) in addition to `audio/*` MIME, so iMessage voice notes whose webhook payload only carries the UTI are now classified as audio in the inbound `<media:audio>` placeholder instead of falling through to the generic `<media:attachment>` tag. Thanks @omarshahine.
-- Active Memory: classify topic-threaded Telegram DM main session keys as direct chats, so recall and transcript persistence run for `agent:main:main:thread:{chatId}:{topicId}` sessions. Fixes #70061. Thanks @vyctorbrzezowski and @worldofgeese.
 - Voice Call/Twilio: honor stored pre-connect TwiML before realtime webhook shortcuts and reject DTMF sequences outside conversation mode, so Meet PIN entry cannot be skipped or silently dropped. Thanks @donkeykong91 and @PfanP.
 - Docs/sandboxing: clarify that sandbox setup scripts (`sandbox-setup.sh`, `sandbox-common-setup.sh`, `sandbox-browser-setup.sh`) are only available from a source checkout, and add inline `docker build` commands for npm-installed users so sandbox image setup works without cloning the repo. Fixes #75485. Thanks @amknight.
 - Google Meet/Voice Call: play Twilio Meet DTMF before opening the realtime media stream and carry the intro as the initial Voice Call message, so the greeting is generated after Meet admits the phone participant instead of racing a live-call TwiML update. Thanks @donkeykong91 and @PfanP.
