fix(compiler-sfc): add support for @vue-ignore in runtime type resolution

[edison1105]

Playground

Summary by CodeRabbit

• New Features

  • Support ignoring runtime type inference for props annotated with @vue-ignore, ensuring those props resolve to an unknown type at runtime.

• Bug Fixes

  • Align behavior across inference paths so @vue-ignore consistently prevents runtime type inference, avoiding unintended prop type resolutions.

• Tests

  • Added coverage to verify that properties marked with @vue-ignore are treated as unknown during prop resolution.

Walkthrough

Adds an ignore pre-check in runtime type inference to return Unknown when a node has a leading "@vue-ignore" comment, and extends tests with a case covering TypeScript property signatures using the ignore marker. No public APIs changed.

Changes

Cohort / File(s)	Summary
Runtime type resolution logic packages/compiler-sfc/src/script/resolveType.ts	Added a leading-comment check for "@vue-ignore" in inferRuntimeType, returning [UNKNOWN_TYPE] early for annotated nodes. Control flow now bypasses inference for ignored nodes.
Test coverage packages/compiler-sfc/__tests__/compileScript/resolveType.spec.ts	Added test "TSPropertySignature with ignore" validating that /* @vue-ignore */ on a property type results in Unknown for that prop in defineProps.

  RT->>TS: Inspect leading comments
  alt Has "@vue-ignore"
    RT-->>R: Return [UNKNOWN_TYPE] (skip inference)
  else No ignore
    RT->>R: Proceed with normal type inference
    R-->>RT: Inferred runtime type(s)

Poem

I nibbled through types with curious care,
Found a whisper: “vue-ignore” in the air.
Hop! I skip the thicket, Unknown I declare—
Tests now wink, “we saw you there.”
Ears up, code neat, carrots to spare! 🥕✨
