Observability playbook

PostmortemDrafter

When an incident-labeled issue closes, assembles a blameless postmortem timeline from comments, PRs, commits, and deploys.

When an issue labelled incident is closed, reconstructs the incident timeline from the issue body and comments, linked pull requests, commits, CI runs, and deploys in the window. Drafts a blameless postmortem and posts it as an issue comment for humans to edit. Set the repository on the report step after importing.
