The `GlobalStore` was refactored to clearly distinguish between immutable RTL values and mutable user-defined global slots. The `Environment` struct now holds: - `rtl_values`: An immutable `Rc<[Value]>` for pre-defined RTL values. - `user_values`: An `Rc<RefCell<Vec<Value>>>` for user-defined mutable globals. The `GlobalStore` struct now takes both `rtl` and `user` as parameters and uses `rtl_len` to determine which store to access. This change separates concerns and better reflects the immutability of RTL values after the bootstrap phase, aligning with the project's concurrency rules. Documentation in `docs/Analysis_Environment.md` was updated to reflect these structural changes.
