CI: build every push, release only on tag

Was tag-only. Now builds on every push to any branch, uploading the
DLL as a workflow artifact (ClassicAPI-<sha>, ~90-day retention) so
pre-release DLLs are downloadable from the run page without cutting
a tag. Tag pushes still build + stamp the embedded TOC version +
publish the GitHub release.

Renamed release.yml -> build.yml to match the broader role.
