ci(evals): prune duplicate onboarding eval cases and shard the onboarding suite

+### Sharded suites (`shards.js`)
+
+A slow suite can run as several CI jobs. Set `shards: N` on its entry in `scripts/_manifest.js`. The "Compute changed suites" job then puts `<suite>#1` to `<suite>#N` in the matrix when the suite changes, and each job runs only its share of the tests. `release-autopilot-onboarding` has `shards: 3`.
+
+The split is deterministic. Tests go, heaviest first by `vars.max_turns` (20 when unset), to the shard with the fewest turns so far, so the shards take about the same time. Adding or removing a test can move other tests to another shard. Sharding selects tests by `description`, so every test in a sharded suite needs a unique description (a unit test checks this for the onboarding suite).
+
+Each shard writes `<suite>/results.shard-<i>-of-<N>.json`. When you aggregate without `--run`, `aggregate.js` merges a suite's shard files into one score, and it fails if a shard is missing. Run a shard locally with:
+
+```bash
+node scripts/aggregate.js --run --only=release-autopilot-onboarding#2   # shard 2 of the manifest's 3
+node scripts/aggregate.js --run --only=launchdarkly-release-plans --shard=1/2  # any suite, any split
+node scripts/aggregate.js --only=release-autopilot-onboarding             # merge the shard files
+```
+
+An unsharded run of a suite deletes its shard files, and a sharded run deletes its `results.json`, so one score never mixes the two.
