Brandon Lucas 3a22ae089f feat: add drop specialization and ownership transfer optimizations ...

Phase B Performance Optimizations:

Drop Specialization:
- Add specialized decref functions: lux_decref_list, lux_decref_closure,
  lux_decref_string, lux_decref_boxed
- Inline drop logic eliminates polymorphic dispatch through lux_drop
- Forward type declarations (typedef struct X_s X) for proper C ordering

Ownership Transfer (Last-Use Optimization):
- Track variable types in var_types HashMap for type inference
- When assigning let b = a where a is RC-tracked:
  - Unregister source variable from RC cleanup
  - Register destination variable instead
- Prevents double-free and eliminates unnecessary incref/decref pairs

Also:
- Fix type inference for variable references in infer_expr_type
- Add is_rc_tracked() and unregister_rc_var() helper functions
- Update REFERENCE_COUNTING.md with Phase B progress
