/**
* Hidden Thinking Label Extension
*
* Demonstrates `ctx.ui.setHiddenThinkingLabel()` for customizing the label shown
* when thinking blocks are hidden.
*
* Usage:
* pi --extension examples/extensions/hidden-thinking-label.ts
*
* Test:
* 1. Load this extension
* 2. Hide thinking blocks with Ctrl+T
* 3. Ask for something that produces reasoning output
* 4. The collapsed thinking block label will show the custom text
*
* Commands:
* /thinking-label <text> Set a custom hidden thinking label
* /thinking-label Reset to the default label
