@babel/traverse is a CJS package that exports { default: fn }.
In Node ESM (.mts), `import traverse from '@babel/traverse'`
resolves to the module object, not the function, causing
"traverse is not a function" at runtime.

Use `_traverse.default ?? _traverse` to unwrap correctly.

Replace dotenvx with plain pnpm test in pre-commit hook.
Remove @dotenvx/dotenvx devDependency (unused outside hook).

The ssr.external approach only works for single-file runs, not the full
suite with isolate: false. Use runtime typeof check to handle both
native CJS resolution and vite's SSR transform.

Vite's SSR transform wraps CJS module.exports as .default, so the
traverse function ends up at traverseModule.default. Use a simple
fallback pattern that works in both vite and native Node contexts.

import { default as traverse } works correctly with vite's SSR transform
and has proper types. Remove deps.interopDefault: false from both vitest
configs — the default (true) handles CJS interop correctly.
