Add smoke-opencode workflow for OpenCode custom engine integration

[Copilot]

Implements a smoke test workflow validating OpenCode (sst/opencode) as a custom agentic engine via shared workflow configuration.

Implementation

• Workflow: .github/workflows/smoke-opencode.md
  • Imports shared/opencode.md for OpenCode v0.15.13 setup
  • Runs daily, workflow_dispatch, and PR label triggers
  • Tests: GitHub MCP, Serena Go, Playwright, file operations, bash commands
  • Safe outputs: issue creation, PR comments, label application

Custom Engine Constraints

OpenCode runs as a custom engine with these adaptations:

• No network restrictions (custom engines don't support firewall)
• No Tavily MCP (HTTP-based MCP servers unsupported)
• No shared/gh.md import (contains network restrictions)

Configuration

name: Smoke OpenCode
imports:
  - shared/opencode.md
strict: true
sandbox:
  mcp:
    container: "ghcr.io/githubnext/gh-aw-mcpg"
tools:
  github:
    toolsets: [repos, pull_requests]
  playwright:
    allowed_domains: [github.com]
  serena: ["go"]

Compiled workflow: 1,288 lines with automatic OpenCode installation, MCP configuration, and execution steps.
