refactor: simplify Docker build commands and fix version matching

- Remove obsolete .docker/alpine/Dockerfile.protoc (superseded by Dockerfile.source)
- Simplify Makefile commands by removing backward compatibility aliases
  * Replace docker-buildx-source* with shorter docker-dev* commands
  * Replace start/stop with explicit dev-env-start/dev-env-stop commands
- Fix Docker workflow version matching logic to correctly distinguish:
  * 1.0.0 vs 1.0.0-alpha.11 (prerelease detection)
  * Support both v1.0.0 and 1.0.0 formats (with/without v prefix)
  * Reorder case patterns to match prereleases before releases

BREAKING CHANGE: Removed legacy command aliases
- Use 'make docker-dev-local' instead of 'make docker-buildx-source-local'
- Use 'make dev-env-start' instead of 'make start'
