//! Incremental cache-tree update for an on-disk repo (benchmark helper).
//!
//! Loads the index, runs [`write_tree_update_index`] with silent ODB writes, persists the
//! cache-tree extension, and prints the root tree OID on stdout.
//!
//! Run: `cargo run --release -p grit-lib --example write_tree_update -- /path/to/repo`
