Fix TypeScript native module transforms

[biw]

Summary

Fix TypeScript native-wrapper transforms without regressing direct .node ESM imports. The resolver still runs before Vite's asset handling, while the source transform runs after Vite transpiles TypeScript.

What This PR Does

• Makes only resolveId pre-ordered instead of pre-ordering the entire plugin.
• Adds generic Vite 7 and Vite 8 integration fixtures for TypeScript modules that load an addon.node file through require and createRequire.
• Bumps the package version to 2.4.1.

What This Improves

• Native wrapper code is parsed as JavaScript after TypeScript syntax has been removed.
• Direct .node ESM imports continue to resolve before Vite classifies them as generic assets.

What This Does Not Do

• Does not change native-binary discovery, hashing, loader generation, or runtime-sidecar handling.

Important Context

• Plugin-wide enforce: "pre" caused the native source transform to parse raw TypeScript.
• Vite and Rollup support per-hook ordering, so only the resolver needs to run early.

Code To Review Closely

src/index.ts:1934

The resolver retains pre-ordering to intercept direct native ESM imports, while transform keeps Vite's normal ordering.

const resolveId = plugin.resolveId;
if (typeof resolveId === "function") {
  plugin.resolveId = {
    call(context: unknown, ...args: unknown[]) {
      return Reflect.apply(resolveId, context, args);
    },
    handler: resolveId,
    order: "pre",
  } as Plugin["resolveId"];
}

Gotchas, Risks, And Edge Cases

• The integration fixtures use fake binary contents and validate bundling behavior, not loading a compiled native addon at runtime.
• Existing direct native ESM-import coverage remains in the same Vite 7/Vite 8 matrix.

Tests And Regression Coverage

Validation Run

• pnpm test: passed (204 tests).
• pnpm lint: passed (format, lint, and type checks).
• pnpm build: passed.
• pnpm precommit: unavailable; this package does not define that script.

Coverage Assessment

Sufficient. The new fixtures exercise both conventional and createRequire TypeScript native wrappers with Vite 7 and Vite 8, and assert that the hashed native asset is emitted and referenced.

Regressions These Tests Should Catch

• Applying pre-ordering to transform and parsing TypeScript before Vite transpiles it.
• Failing to emit or reference a native asset loaded from TypeScript wrapper code.
• Losing direct .node ESM import compatibility on Vite 7 or Vite 8.

Gaps And Recommended Follow-Up Tests

• Consider a runtime smoke test with a compiled addon when a cross-platform fixture becomes available.

Follow-Up Work
