The `UpvalueAnalyzer` pass is no longer necessary as the binder now directly tracks captures. This commit removes the `UpvalueAnalyzer` struct and associated logic from `src/ast/compiler/upvalues.rs`. The `Binder::bind_root` function now returns the `captures` map, which is then processed by a new `CapturePass` in `src/ast/environment.rs` before type checking. This consolidates capture logic within the binder and its subsequent processing steps.
