Trait Recognizer 

pub trait Recognizer: Send + Sync {
    // Required methods
    fn name(&self) -> &'static str;
    fn id(&self) -> &'static str;
    fn category(&self) -> Category;
    fn scan(&self) -> Result<Vec<Finding>>;
}

A recognizer detects reclaimable disk space from a specific tool or ecosystem.

Recognizers come in two flavors:

• Path-based: scan known fixed paths (caches, model stores)
• Project-based: scan directories for marker files (build artifacts)

Required Methods

fn name(&self) -> &'static str

Human-readable name (e.g., “Xcode DerivedData”).

fn id(&self) -> &'static str

Machine-readable identifier (e.g., “xcode-derived-data”).

fn category(&self) -> Category

Which category this recognizer belongs to.

fn scan(&self) -> Result<Vec<Finding>>

Scan for findings. Returns an empty vec if nothing found.
