Add support for semicolon-terminated statements according to the updated grammar. This change enables executing multiple SQL statements in a single input by separating them with semicolons. Key improvements include: - Update grammar to require semicolons after statements - Add Semicolon token to the tokenizer - Implement error recovery by skipping to next semicolon on parse errors - Create helper functions for checking semicolons in statement parsers - Add tests for multiple statements and error conditions
