fix: implement complete release system with release-plz (#209)

* chore: remove all release infrastructure

Complete removal of release tooling including:
- release-plz configuration
- cargo-dist configuration
- cliff changelog generator
- GitHub Actions workflows for releases
- Debug release scripts

Starting fresh to properly configure release automation

* chore: remove tag-on-merge workflow

Part of complete release infrastructure removal

* chore: complete removal of all release infrastructure

- Remove docker-publish workflow that triggered on releases
- Remove old release process documentation
- Clean slate for new release system

* feat: implement complete release system with release-plz

- Configure workspace versioning (all crates share same version)
- Add release-plz.toml with single tag format (v{version})
- Add cliff.toml for changelog generation
- Add GitHub workflows for release-plz and Docker builds
- Initialize cargo-dist for binary distribution
- Create multi-stage Dockerfile with Alpine

Release flow:
1. Push to main triggers release-plz to create PR
2. PR contains version bumps for all crates
3. Merge creates single tag (v0.x.x format)
4. Tag triggers cargo-dist for binaries and Docker builds
5. All three crates publish to crates.io

* chore: remove duplicate Dockerfile.alpine

* fix: improve release-plz configuration

- Add version_group to ensure all packages share same version
- Add explicit git_tag_enable = true
- Add semver_check for breaking change detection
- Add pr_labels for release PRs
- Add publish_timeout and other best practices from real-world usage

* fix: update release-plz action to latest version v0.5.114

Pin to specific version for reproducible builds

* fix: use floating v0.5 tag for release-plz action

Following pattern used by octocrab and other successful projects.
The docs appear to be incorrect about release-plz/release-plz.
