feat: improve tree-sitter syntax highlighting with named nodes

- Add aliases for keywords (VAR_INPUT, BEGIN, IF, etc.) as named nodes
- Add aliases for built-in types (INT, BOOL, STRING, etc.) as type_builtin
- Add aliases for constants (TRUE, FALSE)
- Add aliases for operators (AND, OR, NOT, MOD)
- Add prefix node for # variable prefix highlighting
- Highlight FB instance names in calls
- Highlight FB parameter names as properties
- Update README with detailed syntax highlighting features
- Update .gitignore for *.wasm files
