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

 ### Syntax Highlighting
 - Full SCL syntax support via tree-sitter
-- ORGANIZATION_BLOCK, FUNCTION_BLOCK, FUNCTION definitions
-- Variable declarations (VAR_INPUT, VAR_OUTPUT, VAR_IN_OUT, VAR_TEMP, etc.)
-- Control structures (IF/THEN/ELSE, CASE, FOR, WHILE, REPEAT)
-- Code regions and comments
-- All SCL data types and operators
+- Block definitions: ORGANIZATION_BLOCK, FUNCTION_BLOCK, FUNCTION
+- Variable sections: VAR_INPUT, VAR_OUTPUT, VAR_IN_OUT, VAR_TEMP, VAR_CONSTANT
+- Control structures: IF/THEN/ELSIF/ELSE/END_IF, CASE/OF/END_CASE, FOR/TO/BY/DO/END_FOR, WHILE/END_WHILE, REPEAT/UNTIL/END_REPEAT
+- Built-in data types: BOOL, INT, DINT, REAL, STRING, TIME, etc.
+- Function block instances highlighted in calls
+- FB parameter names (IN, PT, CU, etc.) highlighted as properties
+- `#` prefix for local variables highlighted
+- Operators: AND, OR, NOT, XOR, MOD
+- Comments: line (`//`), block (`(* *)`), C-style (`/* */`)
