Release v2.4.0

Fixed

• Path alias imports: quick fixes now avoid importing an Angular library from its own barrel and use relative imports inside the same alias root
• Barrel alias safety: directory aliases now fall back to relative imports when the barrel index.ts does not re-export the target module
• Stale index cache entries: cached project files that were moved or deleted while the extension was not running are detected and trigger a full reindex instead of producing broken import paths
• Cross-platform relative paths: relative import generation now uses the shared path helper for consistent Windows path separator handling

Improved

• External library indexing memory usage: library AST source files are released after indexing to keep ts-morph memory growth bounded in large workspaces
