* Implement native Unicode 17 grapheme iteration
Add the CPython extended grapheme state machine, full-codepoint properties, and traced Segment/iterator types with positional index handling. Refresh canonical unicodedata tests through update_lib while retaining pending markers. Include a losslessly range-compressed exact-final property oracle and differential test.
Source-reviewed implementation; candidate runtime validation remains pending. Reference property generation completed against the pinned CPython Unicode extension.

* Bind grapheme Segment methods to the Python object
Use the required Py<Segment> receiver for native descriptors; preserve payload ownership and representation behavior.

* Keep grapheme property regression in test module
Move the existing complete Unicode 17 property regression into the existing cfg(test) module to satisfy strict Clippy. Preserve the fixture, assertions, code-point coverage, and platform-independent provenance line check unchanged.

Replace redundant PySourceLocation, Row, and Column wrappers with the compiler-core re-export of Ruff SourceLocation. Use UTF-8 byte coordinates and retain the empty-source fallback. Share the normalized range conversion while preserving caller validation and signed semantic metadata.
Validation so far: independent source and boundary review, rustfmt, and git diff --check. Runtime validation follows after the shared build target is released.

Share first-error recording between generated-node allocation and synthetic-pass coordinate overflow. Exercise both real compiler-state failure paths in both orders using one MAX_ID location entry.
Validation: focused compiler-state regression, strict codegen all-target Clippy, unchanged full-source seals, rustfmt, and normal pre-commit hooks. No interpreter runtime or broad suite rerun for this error-only change.

* Keep native callable GC traversal off the bind path
Revert method_descriptor and classmethod_descriptor to untracked
payloads. Their only object field, _method_def_owner, points to an
untracked HeapMethodDef.
Restore the derived Traverse for builtin_function_or_method without a
clear implementation. default_dealloc calls the clear slot on every
deallocation, so the custom clear allocated a Vec for each bound builtin.
Use the derived Traverse for builtin_method, skipping the static class.

bytearray.__mod__ copied the format and ran the arguments' __repr__,
__str__, __bytes__ and __index__ without holding an export, so a callback
could clear or extend the format and formatting went on with the old
copy:
fmt = bytearray(b"%a end")
class S:
def __repr__(self):
fmt.clear()
return "E"
fmt % S() # bytearray(b'E end'), fmt left empty
CPython holds a buffer on the format for the whole call, so the resize
fails with BufferError and the format is left as it was. Taking an export
for the duration of __mod__ does the same here, the way bytearray.join
already does for its separator.
This lets test_mod_concurrent_mutation in test_bytes run again.

object_getstate_default kept the __slotnames__ list read-locked while it
looked up each slot attribute. A getter or __getattr__ that changed the
list (as in test_descr.test_issue24097) then waited forever for the write
lock. A non-str entry in a cached __slotnames__ hit an unwrap and
panicked.
Take a reference to each name and drop the lock before the lookup, raise
TypeError for a non-str name, let errors other than AttributeError
propagate, and check the list size after each item, as CPython does.
