Restrict Docker builds to tagged releases only

[Copilot]

Docker builds were triggering on every push and pull request, consuming unnecessary CI resources. Changed workflow to run only on version tags.

Changes

• Removed push.branches: ["main"] trigger from docker.yml workflow
• Removed pull_request trigger from docker.yml workflow
• Retained push.tags: ["v*"] and workflow_dispatch triggers

Docker images now build exclusively on release tags (e.g., v0.1.1) or manual dispatch, not on every commit or PR.

Note

CI workflow scope change for Docker builds

• Restricts .github/workflows/docker.yml triggers to push.tags: ["v*"] and workflow_dispatch
• Removes push on branches (e.g., main) and pull_request triggers, preventing image builds for regular commits/PRs
