Previously, compiled closures were stored as `Value::Object` and then downcasted. This commit introduces a dedicated `Value::Closure` enum variant to represent compiled closures. This improves type safety and simplifies handling of closures throughout the compiler and VM. This change involves: - Updating type definitions to use `Value::Closure`. - Adjusting downcasting logic to directly access the `Closure` struct. - Modifying `run_with_args` and `run_with_args_observed` to expect `Value::Closure` for tail-call targets. - Refining the handling of closures in the `Optimizer` and `Inliner` for better type clarity.
