Collect merge-request-based standup data from GitLab or GitHub. Returns one JSON object: today, previousDays[] with the events of each, todayEvents[], myMrs[] bucketed ready / blocked / draft / stale, reviews[] waiting on you, and blockers[] carrying the error lines read out of each failed pipeline job log.

Call it once at the start of a working day, to write a standup note. It is a snapshot, not a search API: it cannot fetch one named merge request, reach further back than the previous working day, or filter by project.

Read-only, and credentials never come from an argument — they come from the environment or a logged-in gh / glab session. A rejected token, a refused resource or a rate limit fails the call with the host's own message, after two retries on transient server errors. A blocker whose diagnosis could not be fetched is still returned, with job: "unknown", so a red pipeline is never silently dropped.

Posts a finished standup note to a chat webhook. This one has a side effect: it sends a message other people will see, so only call it on a note the user has agreed to send.

The webhook URL is read from STANDUP_WEBHOOK_URL, never from an argument — a webhook URL is a credential, since anyone holding it can post to the channel. Slack and Discord payload shapes are supported; the shape is inferred from the URL host, and kind is only needed for a proxied or self-hosted endpoint whose host gives nothing away — Mattermost and Rocket.Chat take the slack shape. A missing URL, an unrecognised host, or a webhook that rejects the message comes back as an error rather than a silent success.

Returns the note-writing rules — the playbook for turning get_standup_data output into a standup note a person would actually say out loud: how to group the previous day by theme, how to derive today from open merge requests, and how to report a blocker from its job log. Read-only, no arguments, no network. Call it once before writing the first note; the rules do not change between calls.
