Fix JSDoc typeof parameter resolution

[sw1tch3roo]

Fixes #61959

Summary

This PR fixes inconsistent typeof lookup/resolution in JSDoc comments where typeof parameterName would produce "Cannot find name" errors instead of correctly resolving to function parameters.

Problem

Previously, when using typeof in JSDoc type annotations like @return {typeof a}, TypeScript would:

• ❌ Produce error: "Cannot find name 'a'" when no outer variable exists
• ❌ Incorrectly resolve to outer scope variables when they exist
• ✅ But go-to-definition and find-all-references would correctly resolve to the parameter

This inconsistency between type checking and navigation features was confusing for users.

Solution

The fix adds JSDoc parameter resolution logic to the resolveNameHelper function in utilities.ts:

1. Detection: When symbol resolution fails for identifiers in JSDoc typeof contexts
2. Resolution: Look up the identifier as a function parameter using getHostSignatureFromJSDoc
3. Consistency: Now typeof a in JSDoc correctly resolves to parameters, matching navigation behavior

Key Changes

• src/compiler/utilities.ts: Added JSDoc parameter resolution in resolveNameHelper function
• src/compiler/checker.ts: Enhanced existing JSDoc parameter resolution logic
• Tests: Added comprehensive test coverage for both type checking and find-all-references

Before/After

Before:

  /**
   * @param {T} a
   * @return {typeof a}  // Error: Cannot find name 'a'
   */
  function f(a) { return a; }

After:

  /**
   * @param {T} a  
   * @return {typeof a}  // Correctly resolves to parameter
   */
  function f(a) { return a; }

Testing

• ✅ Added jsdocTypeofParameterConsistency.ts compiler test
• ✅ Added jsdocTypeofParameterResolution.ts fourslash test for find-all-references
• ✅ All existing tests pass
• ✅ New baselines show correct type inference: (a: T) => typeof a

This change ensures consistent behavior between type checking and IDE navigation features, resolving the inconsistency reported in #61959.
