[slides] Update AI Engines slide with Pi engine

[github-actions]

Slide Deck Updates

Changes Made

• Added the Pi engine to the "AI Engines" slide (multi-provider agent supporting Copilot, Anthropic, and OpenAI-based models), which was previously missing.
• Clarified that Crush, OpenCode, and other community integrations are samples only and not officially supported, matching docs/src/content/docs/reference/engines.md.

Layout Issues Fixed

• None — Playwright/http-server tooling was unavailable in this sandbox (permission restrictions), so layout was verified via successful Marp HTML build only. The edited slide still has a similarly short bullet list (6 vs 5 items), so overflow risk is low.

Content Sources Reviewed

• docs/src/content/docs/reference/engines.md (source of truth for supported engines)
• docs/slides/index.md (current slide deck)

Verification: Built slides with Marp CLI successfully after the edit. Playwright visual verification could not be run due to sandbox permission restrictions on starting a local HTTP server.
