chore(release): bump to v0.3.7 -- backend version string + winget manifests; fix(ci): winget submission needs a Windows runner

Version bump: backend/main.go latestCLIVersion and the local
winget/manifests/*.yaml mirror to 0.3.7, with the real
InstallerUrl/InstallerSha256 for the cli/v0.3.7 release asset.

CI fix: the first real winget-submission attempt (v0.3.7, now that
WINGET_TOKEN is finally set) failed immediately -- wingetcreate isn't
published as a NuGet/dotnet-tool package at all, it's a native Windows
binary requiring .NET 6 + VC++ Redistributable. `dotnet tool install
--global wingetcreate` on ubuntu-latest could never have worked; this
path was just never exercised before since the empty-token check
always short-circuited it first. Split winget submission into its own
job on windows-latest, downloading wingetcreate.exe directly from its
GitHub release instead of dotnet tool install.
