Force -p:Platform=x64 in workflow dotnet build steps

Project-level dotnet build defaults to AnyCPU and emits to
Craftimizer/bin/Release/, even though the csproj declares
<Platforms>x64</Platforms> and <RuntimeIdentifier>win-x64</RuntimeIdentifier>.
That mismatch silently broke the first v0.1.0 release run
(/JonKazama-Hellion/Craftimizer/actions/runs/387): build succeeded
but 'find Craftimizer/bin/x64/Release -name latest.zip' returned
'No such file or directory' so the release-action got nothing to attach.

Local builds via 'dotnet build Craftimizer.sln' work because solution-
level builds inherit the per-project Platforms list as the default,
which is a different code path from project-level builds.

Add -p:Platform=x64 to both build.yml and release.yml dotnet steps so
the CI build agrees with the find paths in the same workflow.

After this push, the v0.1.0 release can be re-triggered via Gitea's
workflow_dispatch on the tag (Actions UI -> Release -> Run workflow,
pick v0.1.0 from the Ref dropdown). The tag itself stays unchanged.
