change Queryable as_object to return &str instead of &String

[veeshi]

Currently the trait cannot be implemented for object keys that aren't actually a String, (we use Box) this way anything that implements AsRef can implement this trait

Pull Request Overview

This PR updates the Queryable trait and its Value implementation so that as_object returns &str keys rather than &String, allowing any AsRef<str>-backed type (like Box<str>) to implement the trait.

• Changed Queryable::as_object signature from &String to &str
• Updated the Queryable for Value impl to call k.as_str() when building the vector
• Broadens implementability to types beyond String-keyed maps

• [nitpick] The trait method signature has changed to return &str keys—consider updating any associated doc comments to reflect this new behavior and note that implementers now accept any AsRef<str>.

    fn as_object(&self) -> Option<Vec<(&str, &Self)>>;

src/query/queryable.rs:73

• [nitpick] We should add unit tests for types with non-String keys (e.g., Box<str>) to verify that as_object correctly returns &str references in practice.

    fn as_object(&self) -> Option<Vec<(&str, &Self)>>;

Good catch. Thanks for the pr
