- Implement set_f_lineno with stack analysis and deferred unwinding - Add Frame::set_lasti() for trace callback line jumps - Implement co_branches() on code objects - Clear _cache_format in opcode.py (no inline caches) - Fix getattro slot inheritance: preserve native slot from inherit_slots - Fix BRANCH_RIGHT src_offset in InstrumentedPopJumpIf* - Move lasti increment before line event for correct f_lineno - Skip RESUME instruction from generating line events - Defer stack pops via pending_stack_pops/pending_unwind_from_stack to avoid deadlock with state mutex - Fix ForIter exhaust target in mark_stacks to skip END_FOR - Prevent exception handler paths from overwriting normal-flow stacks - Replace #[cfg(feature = "threading")] duplication with PyAtomic<T> from rustpython_common::atomic (Radium-based unified API) - Remove expectedFailure from 31 now-passing jump tests
