What c-review does
Runs in the main conversation (invoke via `/c-review:c-review`). Orchestrator owns the `Task*` ledger as bookkeeping for retries; workers and judges have no Task tools. Workers and judges are named plugin subagents (`c-review:c-review-worker`, `c-review:c-review-dedup-judge`, `c-review:c-review-fp-judge`); tool sets are declared in `plugins/c-review/agents/*.md`. Findings are exchanged via markdown-with-YAML files in a shared output directory.
