feat: optimize package naming for CI builds

- Truncate commit hash to 10 characters for better readability
- Add debug output to show when CI build number vs timestamp is used
- Prioritize GITEA_RUN_NUMBER for cleaner build identifiers
- Expected result: apt-ostree_0.1.0-2+build109.6de675810a_amd64.deb
