Compiler parity: codegen and symboltable changes 
- Docstring dedent (clean_basic_doc): match indentation stripping
- StopIteration wrapper for generators/coroutines (PEP 479)
- Constant condition elimination: if False:/while True: optimization
- do_not_emit_bytecode for dead code paths with sub_table consumption
- POP_JUMP_IF_NONE/NOT_NONE for `x is None` patterns
- CALL_KW threshold: nelts + nkwelts > 15 (STACK_USE_GUIDELINE/2)
- Dict literal chunking: 17-pair chunks matching flowgraph.c
- PEP 709: inlined comprehensions in function scopes, symboltable comp_inlined
- Optimize %-format to f-string bytecode (optimize_format_str)
- expr_constant: safe tuple folding, elif test walk for sub_table consumption
