agent-evolutions

Apply phase of an agent evolution — diff the winner workspace against the live repo, get explicit user confirmation, copy files in, optionally re-run gates against the live tree. Writes `applied`. Requires `winner` set by `/run-agent-evolution`.

Capture phase of an agent evolution — discuss the objective, gates, rubric, scope, and budget; write `.agents/evolutions/<id>-<slug>/{evolution.yaml, EVOLUTION.md}` only on explicit user agreement. Pairs with `/run-agent-evolution` (next) and `/apply-agent-evolution` (later).

Run phase of an agent evolution — plan a batch of up to `budget.parallel` variants, dispatch sub-agents in parallel to materialize and evaluate them, learn from results, repeat until budget / wall-clock / plateau. Writes `winner` on a clean stop. Requires an evolution captured via `/new-agent-evolution`; `/apply-agent-evolution` lands the winner afterward.
