fix(oxlint): Fix type-aware linting crash when Vue files are present

[Copilot]

The --type-aware linting functionality was crashing when projects contained Vue files. The issue occurred because the tsgolint module was attempting to process all lintable files (including .vue files) for type checking, but SourceType::from_path() only supports JavaScript and TypeScript file extensions.

Problem

When running oxlint --type-aware on a project containing Vue files, the program would fail with an error because:

1. The file walker collects all lintable files, including .vue files (which are in LINTABLE_EXTENSIONS)
2. The tsgolint functionality tries to process all collected files for type checking
3. SourceType::from_path() returns an error for .vue files since they're not valid JS/TS extensions
4. This caused the type-aware linting to fail entirely

Solution

Added a filter in tsgolint.rs to only process files that can be handled by SourceType::from_path() (i.e., JavaScript and TypeScript files) before sending them to tsgolint for type checking. Vue files and other non-JS/TS files are now filtered out during type-aware linting while still being processed correctly by the normal linter.

The fix is minimal and surgical - only 4 lines added to filter the file paths before processing, ensuring that:

• Normal linting continues to work with all file types including Vue files
• Type-aware linting only processes JS/TS files and no longer crashes
• All existing functionality is preserved

Testing

• All existing tests pass (124/124)
• Manual testing confirms the fix works with mixed file types
• Type-aware linting now gracefully handles projects with Vue files

Fixes #13003.

Pull Request Overview

This PR fixes a crash in the --type-aware linting functionality when Vue files are present in the project. The issue occurred because the type-aware linter was attempting to process all lintable files (including Vue files) through SourceType::from_path(), which only supports JavaScript and TypeScript extensions.

• Added a filter to exclude non-JS/TS files from type-aware processing
• Imported SourceType to enable the filtering functionality
• Preserved normal linting behavior for all file types including Vue files
