Closes#30045. Based on @qike-ms's PR #30141.
Telegram status callbacks (lifecycle, compression, context-pressure)
used to append a fresh bubble on every emit. Now adapter tracks
{(chat_id, status_key) -> message_id}; first call sends, subsequent
calls edit. Failed edits drop the cache entry and fall through to a
fresh send.
- gateway/platforms/telegram.py: send_or_update_status() (+34 LOC)
- gateway/run.py: route _status_callback_sync through it when the
adapter supports it; plain adapter.send() otherwise (+15 LOC)
- 5 tests covering first send / edit-in-place / edit-failure fallback
/ distinct key & chat isolation
