Claude Code Review

This PR updates partyserver and related Cloudflare packages. The changes look good overall - primarily dependency updates with minimal code changes.

Key Changes:

• partyserver: 0.0.75 → 0.1.0 (better default Env typing to Cloudflare.Env)
• @cloudflare/workers-types: 4.20251127.0 → 4.20251221.0
• wrangler: 4.51.0 → 4.56.0
• @cloudflare/vite-plugin: 1.15.3 → 1.19.0
• @cloudflare/vitest-pool-workers: 0.10.11 → 0.11.1

Code Changes:

1. packages/agents/src/index.ts: Type improvements from partyserver update - Env parameter now properly defaults to Cloudflare.Env (lines 297-300)
2. packages/agents/src/ai-chat-agent.ts: Same Env typing improvement (lines 139-142)
3. guides/human-in-the-loop/src/server.ts: Removed unused imports (createUIMessageStream, createUIMessageStreamResponse)

Assessment:
✅ No substantive issues found
✅ Breaking change is appropriate (partyserver 0.0.x → 0.1.0)
✅ Unused imports cleaned up
✅ Type safety improvements from better Env defaults

The PR is ready to merge.
