Add fuzz testing and parser edge case regression tests Fuzz targets (cargo +nightly fuzz): - fuzz_lexer: lexer must never panic on arbitrary input - fuzz_parser: parser must never panic on arbitrary input - fuzz_compile: full pipeline (parse → analyze → IR → optimize → codegen → assemble → link) must never panic Results: 3.3M iterations across all targets, zero crashes. Seed corpus from all 7 examples + crafted edge cases. 11 new parser edge case tests: - draw_followed_by_statement: regression for keyword-arg lookahead bug - draw_with_frame_followed_by_statement: same with frame: arg - nested_if_else_chain: 3-deep else-if chain - deeply_nested_blocks: 4-deep nested if blocks - empty_function_body: fun noop() {} - empty_state_handlers: on enter/exit/frame {} - button_start_in_condition: "start" keyword as button name - button_select_in_condition: "select" keyword as button name - multiple_draws_in_sequence: 3 draws followed by assignment - parser_no_panic_on_garbage: 25 malformed inputs - lexer_no_panic_on_garbage: 10 malformed inputs 221 tests total, all pre-commit checks pass. https://claude.ai/code/session_01W6eQFStA66EuMKHUFo2rx3
