Replace incremental build scenario with binary size (#64453)

## Summary

- remove the `incremental-editor` Wezel scenario and its source patch
- build the `zed` binary with the release profile
- track both its original size and the size of a separately stripped
copy
- lock the `exec` and `filesize` foragers and regenerate the experiment
schema
- skip the full Zed test suite when a pull request changes only
`.wezel/**`

## Validation

- `wezel project tool sync`
- `wezel experiment lint`
- `wezel project status`
- smoke-tested the copy-and-strip command against a debug-symbol-bearing
executable on macOS
- `rustfmt --check tooling/xtask/src/tasks/workflows/run_tests.rs`
- `actionlint .github/workflows/run_tests.yml`
- exercised the CI path filter with Wezel-only, mixed, docs-only, and
source-only file sets

The full Zed release build was not run locally.
