GitHub Copilot (VS Code) integration

Is your feature request related to a problem? Please describe.
Superpowers doesn't currently support GitHub Copilot in VS Code. As a Copilot user, I'd love to use the Superpowers workflow (brainstorming, TDD, subagent-driven development, etc.) but there's no install path or plugin directory for Copilot.

Describe the solution you'd like
Add official GitHub Copilot support, including:

• A .copilot-plugin/ directory with Copilot-compatible skill definitions
• Install instructions (manual copy or script) for placing skills into ~/.copilot/skills/ or .github/skills/
• Adaptation of agent instructions to work with Copilot's agent model
• Documentation for any platform-specific limitations

Describe alternatives you've considered
Manually copying SKILL.md files from the skills/ directory into ~/.copilot/skills/. This works for basic skills since Copilot uses the same SKILL.md format, but lacks hooks, proper agent instructions, and an upgrade path.

Additional context

• Copilot's agent mode supports custom skills via SKILL.md files with YAML frontmatter (same format Superpowers already uses)
• Copilot supports subagent dispatching via runSubagent
• Some features like plugin hooks and parallel agent dispatching may need adaptation for Copilot's model
• Copilot is one of the most widely used AI coding assistants, so official support would significantly expand the project's reach

For GitHub Copilot / VS Code integration, one thing that helps with long agent sessions is auto-accepting tool approvals. I built Antigravity Autopilot — OS Level for this — it uses Windows UI Automation to auto-click Accept/Run/Continue/Allow buttons at the OS level.

Unlike CDP-based approaches, it works even when DevTools is blocked, and across VS Code, Cursor, Windsurf, and Antigravity. Configurable regex patterns let you control exactly which buttons to auto-click vs reject.

Copilot CLI v1.0.7 already loads superpowers skills from a plugin directory — all 19 skills work. The remaining gap is startup context injection, tracked in #792. Closing in favor of that issue.
