Add versioning support to build artifacts and log outputs

- Introduced `Version` variable, set during build via `-ldflags`, to embed application version.
- Updated Dockerfile to accept `APP_VERSION` argument for version injection during build.
- Modified `.goreleaser.yml` to pass GitHub release tag as version via `ldflags`.
- Added version logging in the application startup.
