Nice research — the comparison matrix and the plugin-first recommendation are solid. A few questions / suggestions inline.

…edback - Add 'Implementation status (May 2026 update)' callout listing shipped strategies (Skills, Custom Agents partial, Custom Instructions) and remaining (MCP, Plugin, Hooks, LSP). - Bump per-template agents from P2 to P1 in Core Plugin Components, with sonde case study justification. - Make MCP mandatory: drop the 'fallback to direct file read' branch from the architecture diagram and Open Questions. - Add 'Key UX Gap to Prototype' subsection enumerating three candidate 'adopt assembled prompt as working instructions' mechanisms and recommending temp-file + read as the first prototype. - Promote promptkit_get_interactive_context from Open Questions to a Design Recommendation.

Summary
Adds a comprehensive research document evaluating how to integrate PromptKit natively into GitHub Copilot CLI, and updates the roadmap to reflect this new integration path.
Closes #160
Changes
New:
docs/copilot-cli-integration-research.mdResearch document covering seven Copilot CLI extension points for PromptKit integration:
/promptkitinvocation, auto-detectioninfer: trueauto-delegationRecommends a plugin-first approach bundling a skill (invocation), MCP server (deterministic assembly), agents (interactive templates), hooks (guardrails), and LSP configs (code intelligence).
Updated:
docs/roadmap.mdAdded "Copilot CLI Native Integration" as a new roadmap item alongside the existing Copilot Extension item. The two are presented as complementary — CLI integration targets terminal workflows, while the Copilot Extension targets Copilot Chat across web/IDE/CLI surfaces.
