Struct DefaultFileStatisticsCache 

pub struct DefaultFileStatisticsCache { /* private fields */ }

Default implementation of FileStatisticsCache

Stores cached file metadata (statistics and orderings) for files.

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)

Uses DashMap for lock-free concurrent access.
