* 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.

* Use explicit object receivers for Segment descriptors
Keep the inherent impl on the local payload and receive &Py<Self>, as required for stdlib classes outside the VM crate.

* Mark grapheme property lookups as must-use
Satisfy strict Clippy for the three pure property functions without changing their behavior.

* Enable validated Unicode grapheme canonical tests
Remove seven stale expected-failure markers through update_lib metadata after native property parity, canonical methods, full Unicode 17 grapheme corpus, and reference-cycle GC validation.

* Accept platform line endings in grapheme oracle header
Compare the complete provenance line without its line ending so the same exact Unicode 17 reference is accepted after Windows checkout conversion. Keep the complete code-point property sweep unchanged.

* 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.

* Fix deprecated PyO3 code input import in benchmarks
Use the canonical code module path introduced in PyO3 0.30 without suppressing deprecation warnings.

Alias criterion to codspeed-criterion-compat so the existing benchmark suites can be measured by CodSpeed with CPU simulation on every pull request, and add the workflow running them.

Change benchmark interpreter from without_stdlib to with_init to load
Rust-optimized native modules like _json, ensuring benchmarks measure
actual optimized performance rather than pure Python fallbacks.

Update the actual benchmark harnesses.
Because the internal APIs previously used are no longer available, I
opted to use `compile` and `exec` from within the CPython context to
compile and execute code. There's probably more overhead to that than
the internal API had, but that overhead should be consistent per
benchmark.
If anyone cares about hyperoptimizing benchmarks then they can optimize
the harness as well.
