build: tolerate ignored files in nano-staged hooks

`oxfmt`/`oxlint` exit with an error when every staged file is ignored by
the formatter/linter config, which breaks commits that only touch
`test/e2e/fixtures/**`. Pass `--no-error-on-unmatched-pattern` to both so
fixture-only commits no longer fail the pre-commit hook.
