Priorities

A single ranked queue, highest-value first. Each item links a scoped issue the loop can build and CI can verify. The planner keeps this current; the builder takes the top item whose issue is still open.

<!-- Seed this with a few real items to give the loop a running start, e.g.: 1. Add retry with backoff to the HTTP client — #123 2. Document the config file format — #124 3. Fix flaky timeout in the cache tests — #125 The planner will re-rank, drop completed items, and file issues for new gaps. Reorder or edit this file at any time to redirect the loop. -->
