Introduces the `TypeChecker` struct and its associated `TypeContext` for performing static type analysis on the abstract syntax tree. This change includes: - A new `type_checker.rs` module. - Integration of `TypeChecker` into the `Environment::compile` method. - Updates to `Environment` to manage global types. - Renaming `bound_nodes.rs`'s `BoundNode` to `TypedNode` to reflect its type-checked nature. - Refinements in binder and macro expansion to accommodate type information.
