1a028f7f03 [internal] Add a skill for benching changes in a sandbox (#95943)
Vibed. This should help with running React PRs on sandboxes to measure
impact on `bench/`.

## Usage

```
use bench skill to to measure impact of https://github.com/react/react/pull/37066
```

- Should be able to point at React or Next PRs
- Compares against mergebase
- Grabs React builds from CI when possible
- Before benching, asserts both React builds are green, or that tests
pass
- Runs on many sandboxes with interleaved runs
- Caches reusable stuff (builds) between sandboxes
- Uses `bench/` examples with realistic payloads

## Test Plan

Running a bench:

/>

Bench that shows good results:

/>

Neutral bench:
