Joshua Megnauth 6493f9a31d fix: Swapcase must handle multibyte expansions (#7559) 
`swapcase` used `to_ascii_lowercase` and uppercase to swap cases. This
is fine for ASCII, but code points may expand into multiple bytes which
leads to incorrect case swaps for some languages. The fix is to use
`to_lowercase` and `to_uppercase` instead.

Unfortunately, this leads to a realloc in `swapcase` when bytes are
expanded.

Part of #7526.

Jeong, YunWon 844fdf3a8d Bytecode parity (#7536) 
* Add CFG block splitting, jump threading, backward jump normalization, genexpr StopIteration wrapper

- split_blocks_at_jumps: split blocks at branch points so each has one exit
- jump_threading: thread jumps through single-jump blocks (flowgraph.c jump_thread)
- Backward conditional jump normalization: invert and create NOT_TAKEN+JUMP block
- Follow empty blocks in jump-to-return optimization (next_nonempty_block)
- Add PEP 479 StopIteration handler to compile_comprehension for generators

* Add ConstantData::Slice and constant slice folding

- Add Slice variant to ConstantData and BorrowedConstant
- Fold constant slices (x[:3], x[1:4]) into LOAD_CONST(slice(...))
- Marshal serialization/deserialization for Slice type
- Box::leak in borrow_obj_constant for PySlice roundtrip

* Add duplicate_exits_without_lineno (disabled) and Block: Clone

Prepare infrastructure for exit block duplication optimization.
Currently disabled pending stackdepth integration.

* Improve codegen bytecode parity

Add Frozenset to ConstantData, BorrowedConstant, and marshal support.
Actual frozenset folding (BUILD_SET + CONTAINS_OP → LOAD_CONST frozenset)
requires VirtualMachine for element hashing and is deferred.

Jeong, YunWon 5433a3d08c Bytecode parity (#7507) 
* Bytecode parity phase 3

Compiler changes:
- Emit TO_BOOL in and/or short-circuit evaluation (COPY+TO_BOOL+JUMP)
- Add module-level __conditional_annotations__ cell (PEP 649)
- Only set conditional annotations for AnnAssign, not function params
- Skip __classdict__ cell when future annotations are active
- Convert list literals to tuples in for-loop iterables
- Fix cell variable ordering: parameters first, then alphabetical
- Fix RESUME DEPTH1 flag for yield-from/await
- Don't propagate __classdict__/__conditional_annotations__ freevar
  through regular functions — only annotation/type-param scopes
- Inline string compilation path

* Skip test_thread_safety in _test_multiprocessing

SIGSEGV in _finalizer_registry dict access under aggressive GC
and thread switching. Root cause is dict thread-safety in VM.

* Skip list→tuple optimization for async for; propagate future_annotations to nested scopes

Jeong, YunWon e5272365af Fix GC TOCTOU race in collect_inner referent traversal (#7511) 
Pre-compute referent pointers once per object in step 3 and reuse
them in step 4 (BFS reachability). Previously, gc_get_referent_ptrs()
was called independently in both steps. If a dict's write lock state
changed between the two calls (e.g., held by another thread during
one traversal but not the other), the two traversals could return
different results. This caused live objects to be incorrectly
classified as unreachable and cleared by GC.

Jeong, YunWon 1bf829a456 Bytecode parity (#7504) 
* Match CPython LOAD_SPECIAL stack semantics for with/async-with

LOAD_SPECIAL now pushes (callable, self_or_null) matching CPython's
CALL convention, instead of a single bound method:
- Function descriptors: push (func, self)
- Plain attributes: push (bound, NULL)

Updated all with-statement paths:
- Entry: add SWAP 3 after SWAP 2, remove PUSH_NULL before CALL 0
- Normal exit: remove PUSH_NULL before CALL 3
- Exception handler (WITH_EXCEPT_START): read exit_func at TOS-4
  and self_or_null at TOS-3
- Suppress block: 3 POP_TOPs after POP_EXCEPT (was 2)
- FBlock exit (preserve_tos): SWAP 3 + SWAP 2 rotation
- UnwindAction::With: remove PUSH_NULL

Stack effects updated: LoadSpecial (2,1), WithExceptStart (7,6)

* Normalize LOAD_FAST_CHECK and JUMP_BACKWARD_NO_INTERRUPT

Add LOAD_FAST_CHECK → LOAD_FAST and JUMP_BACKWARD_NO_INTERRUPT →
JUMP_BACKWARD to opname normalization in dis_dump.py. These are
optimization variants with identical semantics.

* Add EXTENDED_ARG to SKIP_OPS, normalize LOAD_FAST_CHECK and JUMP_BACKWARD_NO_INTERRUPT

* Remove duplicate return-None when block already has return

Skip duplicate_end_returns for blocks that already end with
LOAD_CONST + RETURN_VALUE. Run DCE + unreachable elimination
after duplication to remove the now-unreachable original return
block.

* Improve __static_attributes__ collection accuracy

- Support tuple/list unpacking targets: (self.x, self.y) = val
- Skip @staticmethod and @classmethod decorated methods
- Use scan_target_for_attrs helper for recursive target scanning

* Use method mode for function-local import attribute calls

Function-local imports (scope is Local+IMPORTED) should use method
mode LOAD_ATTR like regular names, not plain mode. Only module/class
scope imports use plain LOAD_ATTR + PUSH_NULL.

* Optimize constant iterable before GET_ITER to LOAD_CONST tuple

Convert BUILD_LIST/SET 0 + LOAD_CONST + LIST_EXTEND/SET_UPDATE + GET_ITER
to just LOAD_CONST (tuple) + GET_ITER, matching CPython's optimization
for constant list/set literals in for-loop iterables.

Also fix is_name_imported to use method mode for function-local imports,
and improve __static_attributes__ accuracy (skip @classmethod/@staticmethod,
handle tuple/list unpacking targets).

* Fix cell variable ordering: parameters first, then alphabetical

CPython orders cell variables with parameter cells first (in
parameter definition order), then non-parameter cells sorted
alphabetically. Previously all cells were sorted alphabetically.

Also add for-loop iterable optimization: constant BUILD_LIST/SET
before GET_ITER is folded to just LOAD_CONST tuple.

* Emit COPY_FREE_VARS before MAKE_CELL matching CPython order

CPython emits COPY_FREE_VARS first, then MAKE_CELL instructions.
Previously RustPython emitted them in reverse order.

* Fix RESUME AfterYield encoding to match CPython 3.14 (value 5)

CPython 3.14 uses RESUME arg=5 for after-yield, not 1.
Also reorder COPY_FREE_VARS before MAKE_CELL and fix cell
variable ordering (parameters first, then alphabetical).

* Address code review feedback from #7481

- Set is_generator flag for generator expressions in scan_comprehension
- Fix posonlyargs priority in collect_static_attributes first param
- Add match statement support to scan_store_attrs
- Fix stale decorator stack comment
- Reorder NOP removal after fold_unary_negative for better collection folding

* Fold constant list/set/tuple literals in compiler

When all elements of a list/set/tuple literal are constants and
there are 3+ elements, fold them into a single constant:
- list: BUILD_LIST 0 + LOAD_CONST (tuple) + LIST_EXTEND 1
- set:  BUILD_SET 0  + LOAD_CONST (tuple) + SET_UPDATE 1
- tuple: LOAD_CONST (tuple)

This matches CPython's compiler optimization and fixes the most
common bytecode difference (92/200 sampled files).

Also add bytecode comparison scripts (dis_dump.py, compare_bytecode.py)
for systematic parity tracking.

* Use BUILD_MAP 0 + MAP_ADD for large dicts (>= 16 pairs)

Match CPython's compiler behavior: dicts with 16+ key-value pairs
use BUILD_MAP 0 followed by MAP_ADD for each pair, instead of
pushing all keys/values on the stack and calling BUILD_MAP N.

* Fix clippy warnings and cargo fmt

* fix surrogate
