COMMENT_BODY="đŗ **Docker Image Build Triggered**
This PR triggered a Docker image build because of the \`+docker\` suffix in the title.
**Expected Image Tags:**
- \`ghcr.io/${{ github.repository_owner }}/zen-mcp-server:pr-${{ github.event.pull_request.number }}\`
- \`ghcr.io/${{ github.repository_owner }}/zen-mcp-server:main-${{ github.sha }}\`
**To test the image after build completes:**
\`\`\`bash
docker pull ghcr.io/${{ github.repository_owner }}/zen-mcp-server:pr-${{ github.event.pull_request.number }}
\`\`\`
**Claude Desktop config for testing:**
\`\`\`json
{
\"mcpServers\": {
\"gemini\": {
\"command\": \"docker\",
\"args\": [
\"run\", \"--rm\", \"-i\",
