Adds `egui_extras` to Cargo.toml and Cargo.lock to enable enhanced table
widgets.
Also introduces a new `StateTab` enum and integrates the
`egui_extras::TableBuilder` to display global variables in a structured
table within the application's state panel. This enhances the debugging
and introspection capabilities of the compiler UI by providing a clear
view of the environment's global state.
