Trait FileStatisticsCache 

pub trait FileStatisticsCache: CacheAccessor<Path, CachedFileMetadata> {
    // Required method
    fn list_entries(&self) -> HashMap<Path, FileStatisticsCacheEntry>;
}

A cache for file statistics and orderings.

This cache stores CachedFileMetadata which includes:

• File metadata for validation (size, last_modified)
• Statistics for the file
• Ordering information for the file

If enabled via CacheManagerConfig::with_files_statistics_cache this cache avoids inferring the same file statistics repeatedly during the session lifetime.

The typical usage pattern is:

1. Call get(path) to check for cached value
2. If Some(cached), validate with cached.is_valid_for(&current_meta)
3. If invalid or missing, compute new value and call put(path, new_value)

See crate::runtime_env::RuntimeEnv for more details
