💡 What: Changed NodeModulesScanner and CacheScanner from actor to struct to enable true parallel scanning.

🎯 Why: In Swift structured concurrency, using withTaskGroup inside an actor and calling its own methods (like findNodeModules) forces all child tasks onto the actor's single executor. This inadvertently serialized the blocking I/O operations (FileManager.default), completely preventing parallel execution. Since neither type has mutable state, converting them to structs solves this.

📊 Impact: Significantly speeds up scanning (especially node_modules scanning on large file trees) by allowing tasks to truly run concurrently across the cooperative thread pool.

🔬 Measurement: Run a scan over a large directory with many node_modules. Observe CPU core utilization (should be multithreaded) and overall wall-clock completion time.
