Apply clippy suggestions

- Use `BTreeMap::entry` API in `update_item`
- Replace `or_insert_with(Vec::new)` with `or_default`
- Iterate over map values instead of key-value pairs
- Use `std::io::Error::other` for custom errors
- Simplify filter logic with direct predicate
- Replace manual `Into` implementation with `From`
- Remove unnecessary explicit returns
