feat: post scheduled-run report to a configured Slack channel (#83)

* Post scheduled-run reports to a Slack channel

Scheduled runs previously had no source channel and finished silently
in the dashboard. Allow an automation to post its final report to a
configured Slack channel as the bot, reusing existing Slack plumbing
instead of the deferred run-completion webhook.

Refs: #82

* Reconcile Slack report feature with dev merge

Dev refactored slack_thread_reply to async and already added
post_slack_top_level_message_with_ts; drop the duplicate definition
and await the tool in the feature's tests.

Refs: #82

* Harden scheduled Slack report channel posting

The no-thread_ts top-level path fired for every slack_thread_reply call
during a scheduled run, spraying disconnected messages and dead
interactive buttons into the report channel. Cap top-level posts at one
per run and drop options/plan_approval blocks in that mode, so the
mechanism (not just the prompt) enforces a single clean report. Also
tighten the channel-ID regex to require a leading letter and document
why top-level posts store no run mapping.

Refs: #82
