CI/CD improvement
Small infrastructure-only release - no user-facing changes to the app itself.
What changed
- Docker images are now tagged with their exact release version on every published GitHub Release (e.g. this release produces
ghcr.io/kazwahs/arrvantage:v1.0.1), in addition to the existing:latesttag. Previously only:latestand a commit-SHA tag were published, with no way to pull a specific pinned version.
This is purely a build/publish pipeline change - see v1.0.0 for the actual feature set.
