The finished-turn digest ('🧠 N thoughts · 💬 N notes · 🛠️ N tool calls ·
⏱️ Ns') was synthesized onto three surfaces: Slack's Block Kit card footer
(removed in #123851), Discord's final-answer subtext, and a duplicate Telegram
implementation added to match Discord.
Nothing gated it — no config key for the receipt has ever existed on any
channel — so PR #122976, which deleted it from Slack's native progress surface,
could only ever be a partial removal. Finish it: live progress surfaces keep
their in-flight indicators, and a finished turn leaves the answer with nothing
synthesized appended.
Telegram's window collapsed *into* the digest, so it now retires like every
other surface; Discord already discarded its draft after the final landed. The
core tracker keeps only the live counters Slack's working footer reads.
