Expand description

Policy knobs that mirror the non-callback fields of C littlefs’ struct lfs_config.

Config deliberately remains only the physical geometry. That keeps the old API and all block devices simple, while this type carries the settings that affect formatting, mounting caches, metadata commit padding, write thresholds, and the limits recorded in the superblock. The default values match the C fixture geometry used by the test oracle, with cache/prog sizes kept at the current low-memory Rust defaults.
