Pull Request Overview

This PR removes the deprecated %runtime directive functionality from the RustyLR parser generator. The directive previously allowed switching between compile-time and runtime table generation, but this feature has been removed entirely.

• Removed all references to the %runtime directive from lexer, parser, and grammar structures
• Simplified state type definitions by removing generic parameters for state and rule indices
• Updated bootstrap tests to remove runtime configuration options
