build(release): prepare Windows CUDA wheel metadata

[IvanaGyro]

Stack

master → #1110 → codex/windows-msvc-cuda-stack (#1116 patch) → #1117 → #1118 → #1119 → #1113

Depends on #1118 and is the final implementation layer before workflow-only #1113.

Summary

• teach the CUDA release-manifest rewrite to emit Windows PyPI runtime dependencies and disable unavailable cuQuantum packages;
• preserve the existing Linux RUNPATH/auditwheel rewrite;
• add platform-specific release-manifest tests and the release-only tomlkit dependency;
• keep IPO enabled in the existing Linux release pipeline;
• disable IPO for Windows CUDA release wheels because CUDA 13 device LTO cannot find the NVVM runtime reliably in the split PyPI toolkit layout;
• explicitly keep IPO off in both CPU and CUDA editable-install commands so iterative builds remain incremental.

Compatibility

Windows metadata uses compatible-release pins for CUDA 13 and cuTENSOR. The Python loader then locates those declared distributions directly; it does not scan arbitrary system SDK roots.

Validation

• pytests/prepare_cuda_release_test.py: 3 passed;
• both editable Pixi tasks explicitly pass -DCMAKE_INTERPROCEDURAL_OPTIMIZATION=OFF;
• Linux release metadata retains its prior LTO setting;
• repository-pinned pre-commit hooks pass.

Part of #1114.

Rename the leading-underscore helper

Rename _manifest to a snake_case name without a leading underscore. The canonical repository contract referenced by AGENTS.md explicitly prohibits leading underscores in new identifiers, and this helper is newly introduced in the change.
