feat: accept a precompiled check in the worker's getOptions

[alexander-akait]

Summary

webpack/webpack#22745 adds an optional second argument to this.getOptions: this.getOptions(schema, check). When the precompiled check passes, webpack skips the schema, so schema-utils and ajv aren't loaded. Loaders are starting to pass it (webpack/coffee-loader#240, webpack/postcss-loader#746).

The worker reimplements getOptions, so a loader running under thread-loader would still compile its schema in every worker. The worker's getOptions now takes the same second argument:

• A passing check returns the options without running the schema.
• A failing check, or no check, validates as before, with the same error messages.

Tests

test/options-check.test.js runs a loader through a real worker:

• When the check passes, options that the schema would reject come back without an error. This test fails without the change in src/worker.js.
• When the check fails, the full validation error is reported.

npm run lint and the full suite (17 tests, 6 snapshots) pass locally.

Summary by CodeRabbit

• New Features
  • Loader option handling now supports an optional check that can approve parsed options without schema validation. If the check is missing or does not approve the options, the existing schema validation still applies.

Walkthrough

The loader-context getOptions method now accepts an optional check callback. When a schema is present, it skips schema validation only if check is a function and returns a truthy value for the options. Otherwise, it runs schema validation. New webpack tests exercise trusted options and an invalid numeric name through a warmed worker.

Priority: ⬇️ Low

Merge Risk: ⚪ Minimal · up to d0f9e

No actionable issue is identified with the optional check or its validation fallback; the change is mergeable after normal checks.

[alexander-akait]

codecov/patch reports 0% because src/worker.js runs in a separate worker process, and Jest only collects coverage in its own process. test/options-check.test.js exercises both new branches through a real worker (the first test fails without this change). Project coverage is unchanged at 14.75%.

The lint job's npm audit --omit=dev failure came from fast-uri 3.0.1 and fails on main too. #262 bumps it to 3.1.8, and the same commit is included here.
