release: 0.2.7 (Windows ARM64 restored + CPU label fix) (#37)

* chore(docs): rename benchmark CPU from 7950X3D to 9950X

The "Reproduced on" line in the umbrella + binding READMEs and the
benchmark page on the site listed the wrong AMD CPU. The benchmarks
were actually produced on a Ryzen 9 9950X, not a 7950X3D. Same
column for absolute µs values applies — the speedup ratios in the
tables are unchanged either way because they're relative across
libraries on the same machine.

The performance-regression issue template's CPU example also
updated for consistency (it was a generic placeholder, but matching
the canonical machine makes the example concrete).

* chore(npm): restore Windows ARM64 sub-package + napi matrix entry

npm Support unblocked the `wickra-win32-arm64-msvc` package name and
transferred write access to @kingchenc (placeholder 0.0.1-security
was published from their side; we ship our first real version on
top of that). This re-enables every change 8aa74cb temporarily
backed out for 0.2.1:

- bindings/node/package.json: re-add `aarch64-pc-windows-msvc` to
  napi.triples.additional and `wickra-win32-arm64-msvc` to
  optionalDependencies.
- bindings/node/npm/win32-arm64-msvc/package.json: restored — name,
  cpu = arm64, os = win32, version pinned to the workspace.
- .github/workflows/release.yml: re-enable the
  `windows-11-arm / aarch64-pc-windows-msvc` row in the node-build
  matrix and drop the "temporarily skipped" comment block.

After the next tag-push this binding will be published alongside
the other five platforms and `npm install wickra` on Windows ARM64
will resolve to a native build instead of failing the loader's
optional-dep lookup.

* release: bump workspace + bindings to 0.2.7

Workspace, every binding (Python, Node, six platform stubs incl. the
restored win32-arm64-msvc), and the CHANGELOG all move together to
0.2.7. wickra-win32-arm64-msvc is now part of the standard publish
matrix and will land on npm alongside the other five binaries.

The 0.2.7 CHANGELOG entry consolidates the two changes this cycle:
- Windows ARM64 binding restored (npm Support unblocked the name).
- Benchmark CPU label corrected (Ryzen 9 9950X, not 7950X3D).

+### Added
+- **Windows ARM64 is back.** npm Support unblocked the
+  `wickra-win32-arm64-msvc` sub-package name (same path
+  `wickra-win32-x64-msvc` took through 0.1.4) and transferred write
+  access to @kingchenc. 0.2.7 ships the binding for
+  `aarch64-pc-windows-msvc` alongside the existing five platforms:
+  the `napi.triples.additional` entry, the `optionalDependencies`
+  pin, the `bindings/node/npm/win32-arm64-msvc/` sub-package and the
+  `windows-11-arm` row of the release.yml node-build matrix are all
+  restored from 8aa74cb. `npm install wickra` on Windows ARM64 now
+  resolves to a native build instead of failing the loader's
+  optional-dep lookup. PyPI's `win_arm64` wheel was unaffected and
+  carries through as before.
+
+### Changed
+- **Benchmark CPU renamed.** The "Reproduced on" line in every
+  README listed an AMD Ryzen 9 7950X3D; the canonical machine is
+  actually a Ryzen 9 9950X. Speedup ratios in the tables are
+  unchanged (they're relative across libraries on the same machine),
+  only the labelling is corrected. The performance-regression issue
+  template's CPU example was updated for consistency.
