AVA stores snapshots in a binary format (`.snap`), which produces no
meaningful diffs and bloats Git history. This replaces AVA with the
built-in `node:test` module, whose snapshot support generates
human-readable text files that are easy to diff and review in pull
requests.
The migration also replaces `@sinonjs/fake-timers` and `execa` with
Node.js built-ins (`node:test` mock timers and `node:child_process`),
removing three dev dependencies total.
- **`tests/index.js`**: Rewritten to use `node:test` with a custom
snapshot serializer that renders strings with actual newlines. Uses
subtests for labeled `stderr`/`stdout` snapshots, and only snapshots
non-empty output.
- **`tests/main-repo-skew.test.js`**: Replace `@sinonjs/fake-timers`
with `mock.timers.enable()` from `node:test`.
- **`tests/README.md`**: Updated documentation to reflect `node --test`
and the new snapshot file.
- **`package.json`**: Remove `ava`, `@sinonjs/fake-timers`, and `execa`
from devDependencies. Update test script to `c8 --100 node --test
tests/index.js`.
- **`tests/index.js.snapshot`**: New text-based snapshot file replacing
binary `tests/snapshots/index.js.snap`.
- **`tests/snapshots/`**: Deleted.
All 22 test scenarios (66 subtests) pass with 100% code coverage.
Closes #344
