fix: add linux-x64 runtime to restore and remove --no-build from publish

Problem:
- CI runs on Linux (ubuntu-latest)
- Local restore was Windows-only, missing linux-x64 runtime
- --no-build skipped rebuild, so publish used stale assets

Solution:
- dotnet restore -r linux-x64 (include Linux runtime)
- Remove --no-build from publish (allow rebuild if needed)

This fixes NETSDK1047 error on Linux CI.
