- Add `cleanup` step: removes per-generation candidate files and
generation_*.jsonl records after they are aggregated into the evidence
file, preventing disk exhaustion (cf. run #1025 at 91% usage).
- Rewrite `deliver` step with mandatory ordering:
1. `git checkout -- .` to discard unrelated working-tree modifications
before staging result files (evidence JSON, champion .push3, manifest).
2. Commit to branch `evidence/evolution-run-{run_id}` (not directly to main).
3. Push and create PR — if this fails, post an error comment and leave the
issue OPEN; do not proceed to step 4.
4. Post summary comment only after PR URL is confirmed, with mandatory
link to the PR.
- Update `products.evidence_file` delivery to PR branch (was "commit to main").
- Update `products.issue_comment` to enforce ordering and non-close-on-failure.
