Add GitHub Actions workflow for approval-gate and P2 harness CI

[caiwang0]

Summary

We do not have a GitHub Actions workflow yet, so the approval-gate / P2 harness tests only run locally today.

We should add a repo CI workflow that runs automatically on push and pull_request so PRs like #11 get real CI coverage in GitHub.

What to add

• A GitHub Actions workflow under

• Trigger on:
• Set up Python
• Run the current repo test commands:

Why

These tests now cover:

• approval confirmation boundaries for persistent changes
• direct policy logic vs the real approval-gate wrapper
• deterministic P2 scenario harness coverage
• setup/integration doc validation tied to the harness flow

Without a workflow, opening a PR does not actually run any of this in GitHub.

Acceptance Criteria

• A GitHub Actions workflow exists and runs automatically on and
• The workflow installs the required Python environment and executes the commands above
• PRs show pass/fail status in GitHub
• The workflow stays local-only and does not require a live Home Assistant instance, MCP server, or networked LLM dependency
