Pull request overview

This PR introduces a new type_def reflection/parsing system (replacing the previous api_def approach) and updates the derive/attribute macros plus downstream crates to use the new model.

Changes:

• Added a new agdb::type_def module (types + tests) to represent reflected structs/enums/traits/functions/impls and expressions.
• Replaced the old agdb_derive::api_def macro implementation with a new type_def_parser pipeline (struct/enum/impl/trait/function/expression parsing).
• Updated agdb and agdb_api code to reference type_def and added new proc-macro attributes (trait_def, fn_def) where needed.
