fix(ci): build win32-arm64 on windows-11-vs2026-arm runner

[cb1kenobi]

Summary

The v2.4.0 publish failed on win32-arm64 with dozens of LNK2001: unresolved external symbol __std_search_1 / __std_find_trivial_1 / __std_find_last_of_trivial_pos_1 errors (failing run).

Root cause: the rocksdb-prebuilds Windows libraries (v11.1.2, built 2026-06-26) are cross-compiled on windows-latest, which now runs the windows-2025-vs2026 image — VS 2026 / MSVC toolset 14.51. That STL enables ARM64 vector algorithms, so the prebuilt rocksdb.lib objects reference __std_* helper symbols that are defined in the linking toolset's STL support lib. The windows-11-arm runner only ships VS 2022 (17.14 / MSVC 14.44), whose ARM64 STL predates those symbols. win32-x64 kept passing because it links on windows-latest with VS 2026.

Fix: switch the win32-arm64 job to the windows-11-vs2026-arm image (actions/runner-images#14225) so the linker toolset matches the prebuilds, same as x64. One-line runner change plus an explanatory comment.

Things to weigh

• windows-11-vs2026-arm is marked public preview (GA'd 2026-06-11), so there is a small risk of queue delays while GitHub balances capacity.
• This fixes CI, but source builds on Windows ARM64 with VS 2022 will still hit the same link error against prebuilds ≥ v11.1.2. The complementary, more durable fix is pinning the rocksdb-prebuilds Windows toolset (e.g. VCPKG_PLATFORM_TOOLSET_VERSION v143) — proposed as a follow-up in rocksdb-prebuilds rather than here.
• CI on this PR does not exercise the fix — only the Publish workflow builds win32-arm64. Verification happens on the next publish attempt.

Cross-model review skipped: single-line CI runner change, no product code.

CI runner fix for the win32-arm64 build — the comment explaining the VS2022-vs-VS2026 ARM64 STL/linker mismatch is clear and checks out. LGTM.
