• Added recursive test discovery.
• Improved the module system with module caching and canonical path resolution.
• Added relative and nested module resolution.
• Improved lexical scoping and control-flow semantics.
• Added and improved runtime diagnostics.
• Fixed numerous parser, lexer, runtime, indexing, numeric, string, map, boolean, and error-handling issues.
• Expanded the test suite substantially.
