pr-tldr

PR TLDR context brief — serves dual purpose: 1. **Committed state (template):** Contains the document skeleton with {{FILL}} markers. The pr-review orchestrator loads this at startup, fills in the markers during Phase 1.5, and overwrites this file with the filled result. 2. **Runtime state (filled):** After the orchestrator writes, subagent reviewers load this file and get the filled context brief. If you're reading this and see {{FILL}} markers, the template has not been filled in — either the orchestrator hasn't run yet, or you're viewing the committed source.
