Update release process (#206)

* Align release process with acor project

- Upgrade GoReleaser to v2 config format (dockers → dockers_v2)
- Enable changelog generation (was skipped)
- Add non-root user to Dockerfile.goreleaser with multi-platform support
- Add release-drafter workflow and config for automated release notes
- Extend Makefile with vet, coverage, race, lint-fix targets

* Fix duplicate govet key in golangci-lint config

* Address code review feedback

- Revert dockers_v2 back to dockers (top-level key unchanged in GoReleaser v2)
- Move breaking_changes to major version-resolver for correct semver

* Keep breaking_changes under minor with explanatory comment

Pre-1.0 project uses minor bumps for breaking changes intentionally.

* Disable fieldalignment to restore original lint behavior

The duplicate govet key merge accidentally activated fieldalignment,
which fails on pre-existing struct layouts outside this PR's scope.
