Refactor: Use new NodeKind and clean up Binder definitions

The Binder and related types have been refactored to use the new
`NodeKind` enum instead of the previous `BoundKind`. This commit updates
all references to use the new structure, ensuring consistency across the
compiler's AST representation.

Key changes include:

- Replacing `BoundKind` with `NodeKind` in the Binder's `bind` and
  `visit` methods.
- Updating pattern matching and field access to reflect the new enum
  variants (e.g., `NodeKind::Def` instead of `BoundKind::Define`).
- Adjusting identifier bindings to use the new `IdentifierBinding` enum.
- Reflecting changes in `DefBinding`, `AssignBinding`, and
  `LambdaBinding` structures.
- Ensuring all newly created nodes use `NodeKind` and the appropriate
  metadata.
