📄 Description

Wire up CI and build rigging to generate a unified Windows installer with x64 and arm64 payloads. At install time, the correct binaries will be installed for the platform.

I was unable to find a combination of hand-picked msvc redist DLLs manually that yielded a working setup on a pristine Windows 11 install, but running the vc_redist installer works reliably, so for arm64, we run the nested installer conditionally. If it is already installed, that step will be skipped.

Fixes #2589

Note: I've tested most of the CI steps in the PR, but signing isn't yet verified and might require minor fixes on the first release after this merges.

Resulting build artifacts: (Note: current OllamaSetup.exe with only x64 binaries is 273MB)
