perf(test): transpile runtime .ts imports with oxc-node instead of tsx

The vitest run loads many .ts files at runtime via Node's native `import()`
(the egg loader resolving fixtures/plugins/app code, plus workspace `src`
exports under node_modules). That path is driven by the `--import` hook in
`test.env.NODE_OPTIONS`, previously `tsx/esm`.

Switch it to `@oxc-node/core/register` (oxc-based, Rust): it is noticeably
faster than tsx and transpiles workspace `src` + decorators correctly.
`@oxc-node/core` >= 0.1.0 fixes the earlier "Cannot read properties of
undefined (reading 'mode')" crash that blocked this swap (the old FIXME).

Full Node-22 suite (isolate:false, --retry 2): same pass/fail result as tsx
(only the env-dependent orm/ssrf failures), with the runtime-transpile portion
~6-13% faster depending on how transpile-heavy the workload is.

tsx is kept as a dependency — it is still used by worker_threads tests and a
few other spots.
