Extract independent bytecode tooling from the Python 3.15 integration. Decode packed import-name arguments without changing older-interpreter fallback behavior, validate canonical opcode numbering, bound deoptimization families to the enum, and reuse parsed CPython analysis. Validated generators reproduce tracked metadata exactly; normal, lazy and eager import fallback matches canonical disassembly. No interpreter, generated metadata or test changes.
