+Switched all 4 services (MD bot, MD database, PD bot, PD database) from manual semver with PR validation to auto-generated CalVer (YYYY.MM.BUILD). Build number increments by counting git tags matching current month pattern. PR/feature branches push to Docker Hub with dev and dev-SHA tags for testing. Main branch pushes latest + CalVer + CalVer-SHA tags. Shared buildcache means PR builds warm the cache for fast main builds. CI auto-commits VERSION file update and creates git tag on merge.
