Deliver ONE digest of everything pending in this workspace to its paired Telegram destination. Counts per queue (overdue with no signal, expectation date past with no signal, waiting on a human decision, delegations delivered and not resolved, attention requests pending), then the top items of the first three queues, at most 7 lines, each with what it is, how many days it has been waiting and its next command taken from timing.available_commands, then a closing line with the total that did not fit. The top items carry exactly the correlated buttons they would carry as an ordinary nudge; the digest never invents an operation. It is recorded in channel_deliveries with source_object_type 'workspace' and trigger 'digest', does NOT consume the 3-per-rolling-day nudge cap, and is capped at ONE digest per channel per day. A scheduled digest also runs weekly, on Monday, at the start of the channel's own local window; this endpoint is the explicit trigger and ignores the window. HONESTY: an overdue line states the expectation and that no signal was recorded, never that a commitment failed or that the other side did not answer; when no expected signal source was declared, the line says so. With nothing pending, no message is sent.
