refactor: separate parser and compiler AST node structures

Simplified the AST architecture by removing the overly complex Node<K,
  T> structure and replacing it with specialized types for
  each phase:

   - Introduced UntypedNode in nodes.rs for the Parser and Macro system,
     eliminating redundant ty: () initializations.
   - Defined a new generic Node<T> in bound_nodes.rs for all compiler
     stages, where T represents the phase-specific metadata.
   - Updated the Binder to act as the bridge between UntypedNode and
     Node<()>.
   - Simplified type aliases: TypedNode, AnalyzedNode, and ExecNode now
     leverage the streamlined Node<T> structure.
   - Updated Parser, Macros, Type-Checker, Optimizer, and VM to reflect
     the architectural changes.
   - Fixed import chains and resolved needless borrows via clippy.

  This change improves type safety, reduces boilerplate code in the
  parser, and makes the compiler stages more idiomatic and
  readable.
