fix(tlon): strip internal tool-trace banners from outbound text

masatohoshino · masatohoshino · commit 370326fb63ee · 2026-07-08T23:39:16.000+09:00
Part of #90684 Wire sanitizeAssistantVisibleText into the tlon outbound adapter's sanitizeText hook, matching the merged sibling channel fixes (Feishu #98705, Mattermost #98693, Slack, Signal, Matrix, IRC). Without the hook, shared delivery passes internal tool-call/reasoning scaffolding verbatim to Tlon end users.
