Add smoke-opencode workflow for OpenCode custom engine integration

[Copilot]

Implementation Complete: smoke-opencode Workflow

• Create .github/workflows/smoke-opencode.md workflow file
  • Configure custom engine with OpenCode shared configuration
  • Set up proper permissions (contents, issues, pull-requests)
  • Configure triggers (schedule: daily, workflow_dispatch, pull_request)
  • Import shared/opencode.md for OpenCode engine setup
  • Configure safe-outputs for issue creation and commenting
  • Define test requirements (removed Tavily and gh.md due to custom engine limitations)
• Compile the workflow to generate .github/workflows/smoke-opencode.lock.yml
• Validate the compiled workflow structure
• Run smoke test validation (fmt, lint, test) - ALL PASSED ✅
• Update schedule to daily per feedback
• Merge main branch (multiple times to keep up-to-date)
• Standardize serena tool configuration syntax to languages: { go: {} }
• Recompile all workflows to apply fixes
• Format and lint all code

Changes Made

1. Updated schedule from every 12h to daily to align with other smoke test workflows
2. Merged latest changes from main branch multiple times:
   • Initial merge with serena standardization
   • Merged main with Docker image TOCTOU fix, campaign cleanup, action version resolution improvements
   • Merged main with validation error improvements, test coverage additions, markitdown fix
3. Updated serena configuration from legacy serena: ["go"] to standard syntax serena: { languages: { go: {} } }
4. Recompiled all workflows (132 workflows) to apply:
   • Custom engine syntax fix
   • Action pin updates
   • Latest compiler changes
5. Formatted all code (JavaScript, JSON, Go)
6. Passed all linting checks

Technical Details

The workflow uses opencode-ai (npm package) as the custom agentic engine:

• Model: anthropic/claude-sonnet-3.5
• Version: 0.15.13
• MCP Integration: Automatic MCP server configuration with format transformation
• Tests: GitHub MCP, Serena Go, Playwright, file operations, bash commands
• Safe Outputs: Issue creation, PR comments, label application

The shared/opencode.md configuration provides a reusable setup for OpenCode custom engine integration that can be imported by other workflows.

Configure open-code to use copilot-cli. Look up the required model names and update the shared agentic-workflow accordingly. @copilot

Configured OpenCode to use GitHub Copilot CLI in commit 7dd48cc. Changes:

• Switched from opencode-ai npm package to gh copilot (GitHub Copilot CLI extension)
• Updated model to gpt-5-mini (Copilot's fastest model, optimized for code tasks)
• Updated version to 0.0.384 (latest Copilot CLI version from constants)
• Simplified MCP config (Copilot CLI uses same format as gh-aw, no transformation needed)
• Uses GITHUB_TOKEN authentication
• Supports multiple models: gpt-5, gpt-5-mini, gpt-5.2, gpt-4.1, Claude, Gemini

@copilot revert 7dd48cc and merge main

Reverted commit 7dd48cc (commit 88a524c) and merged main (commit 933845a). The workflow now uses opencode-ai with anthropic/claude-sonnet-3.5 model as before. Also fixed an unused function lint error from the merge.
