feat: implement custom version calculation with build metadata

- Calculate version as base_version+build_number (e.g., 2.327.1+1)
- Build number increments for each release of the same base version
- Bypasses GitVersion tag conflicts with old v1.x tags
- Docker images use base version, releases use full version with build metadata
