Improve release workflow: detect tag on push, wait for auto-created tag, and robustly handle artifacts/checksums

- Use ref_name when triggered by a tag push; otherwise wait for the auto-created tag and pick the latest v*.*.* tag
- Expose both version and tag as outputs
- Use safer find/cp invocation for release files and add conditional checksum generation (handle missing artifacts)
- Use the full tag (with "v" prefix) when creating the GitHub release
