feat(parser): add TS1363 error code

The span is not correct, but I think this is still better then nothing :)
The span should be only on the specifiers, not on the complete import declaration.

Pull request overview

This PR adds support for TypeScript error code TS1363, which validates that type-only imports cannot mix a default import with named bindings (e.g., import type A, { B } from 'mod' is invalid).

• Implements validation logic in the module record builder to detect and report TS1363 errors
• Adds the new diagnostic message for TS1363
• Updates test cases to remove or comment out previously valid syntax that now correctly produces errors
