When components registering tools unmount during navigation, the tools were removed from the local registry but not cleared from UseAIClient. This caused the AI to call stale tools whose handlers no longer exist, resulting in an infinite "thinking" hang. Handle the hasTools=false transition by calling client.registerTools([]) to clear stale tools from the client instance. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

This is a bug fix PR. When a user visits a page that registers client-side tools and then navigates to another page that has no tools,
useAIdoes not process the unregister call, so the tools from the previous page remain in the agent's tool list. When the agent invokes one of those stale tools, the client-side browser cannot resolve it, causing the AI process to hang indefinitely.🤖 Generated with Claude Code
