Pull request overview

Adds an “API catalog” of type definitions for the Rust agdb_api crate and updates trait type-def generation to produce TypeDefinition implementors that can be enumerated.

Changes:

• Update #[agdb::trait_def] expansion to emit a *Def marker struct implementing TypeDefinition (instead of a __*_type_def() free function).
• Introduce agdb_api::api::Api::type_defs() to return a curated list of (Type, Vec<Impl>) for the public API surface, with tests validating closure/type-graph resolvability and catalog completeness.
• Add/adjust feature-gated exports to make required type/trait defs accessible under the api feature.
