9a0511be0b Align specialization guards and caching with CPython (#7341) 
* vm: complete specialized opcode dispatch paths

* vm: cache LOAD_GLOBAL with dict entry hints

* vm: align adaptive specialization counters with CPython backoff

* vm: apply cooldown counter on specialization success paths

* vm: retain LOAD_GLOBAL specializations on misses

* vm: keep attr and call specializations on guard misses

* vm: retain store-attr and store-subscr specializations on misses

* vm: retain specialization opcodes on generic fallback paths

* vm: align jump-backward specialization defaults with CPython

* vm: retain exact-args call specializations on misses

* vm: retain SEND_GEN specialization on non-coroutine sends

* vm: specialize list.append calls like CPython CALL_LIST_APPEND

* vm: set cooldown on LOAD_ATTR_CLASS specialization

* vm: specialize bound method object CALL paths

* vm: specialize CALL_KW for bound method objects

* vm: use current-state function version for CALL_KW specialization

* vm: align CALL/CALL_KW pyfunction specialization with CPython

* vm: drop call-site identity caches in generic CALL specializations

* vm: align builtin type call specializations with CPython guards

* vm: align builtin CALL guards with CPython self_or_null semantics

* vm: require exact list in CALL_LIST_APPEND fast path

* vm: align CALL builtin/class specialization flow with CPython

* vm: tighten len/isinstance CALL specializations to builtin guards

* vm: gate CALL_BUILTIN_CLASS on type vectorcall like CPython

* vm: run non-py CALL specializations via direct vectorcall

* vm: align class-call specialization branching with CPython

* Fix CI: disable ForIterGen, tighten CALL guards

- Disable ForIterGen specialization (falls through to generic
  path) because inline generator frame resumption is needed
  for correct debugger StopIteration visibility (test_bdb)
- Use downcast_ref_if_exact for PyNativeFunction in CALL
  specialization guards
- Add can_specialize_call guard for class __init__ specialization
- Remove expectedFailure for test_bad_newobj_args (now passing)

ccd377cc47 instruction CACHE (#7251) 
* Emit CACHE code units in bytecode to match CPython 3.14

- Add cache_entries() method to Instruction enum
- Emit CACHE code units after opcodes in finalize_code
- Handle NO_LOCATION (line=-1) in linetable for CACHE entries
- Account for CACHE entries in exception table generation
- Skip CACHE entries in VM execution loop (with jump detection)
- Handle CACHE in InstrumentedLine/InstrumentedInstruction/InstrumentedForIter/InstrumentedNotTaken
- Skip CACHE in monitoring instrumentation phases
- Update co_branches() for cache-adjusted offsets
- Restore _cache_format in Lib/opcode.py
- Remove expectedFailure from test_c_call, test_start_offset

* Use relative jump offsets and fix bytecode layout

- Convert jump arguments from absolute to relative offsets
  in frame.rs, monitoring.rs, and stack_analysis
- Add jump_relative_forward/backward helpers to ExecutingFrame
- Resolve pseudo jump instructions before offset fixpoint loop
- Emit NOP for break, continue, pass to match line-tracing
- Fix async for: emit EndAsyncFor with correct target, add NotTaken
- Fix comprehension if-cleanup to use separate block
- Fix super() source range for multi-line calls
- Fix NOP removal to preserve line-marker NOPs
- Fix InstrumentedLine cache skipping after re-dispatch
- Match InstrumentedResume/YieldValue in yield_from_target
- Remove CALL_FUNCTION_EX cache entry from opcode.py
- Remove resolved expectedFailure markers

* Align CPython 3.14 LOAD_GLOBAL null-bit and RERAISE semantics

* Remove redundant CPython-referencing comments

Clean up comments that unnecessarily mention CPython per project
convention. Replace with concise descriptions of the behavior itself.
