Fixes#1066
## Changes
Done. Here's what was changed:
**`evidence/README.md`**
- Added `"candidate_commit": "abc1234"` to the red-team schema JSON example
- Added `candidate_commit | string | Git commit SHA of the optimizer under test` row to the field table
**`scripts/harb-evaluator/red-team.sh`**
- Captures `CANDIDATE_COMMIT` from `git rev-parse HEAD` at startup (alongside existing `CANDIDATE_NAME`/`OPTIMIZER_PROFILE`)
- Added a new step (9a-pre) that writes `evidence/red-team/YYYY-MM-DD.json` at the end of each run, including `candidate_commit` plus all other schema fields (`candidate`, `optimizer_profile`, `lm_eth_before`, `lm_eth_after`, `eth_extracted`, `floor_held`, `verdict`, `attacks`)

Add evidence/ with subdirs for evolution, red-team, holdout, and user-test.
Each subdir has a .gitkeep and README.md documents the JSON schema for all four
process types so formulas and the planner have a canonical contract to read/write.
