Subagents documentation bug suggests agents can pause for tool permission approval

### Checks

- [x] I have searched [github.com/aws/amazon-q-developer-cli/issues](https://github.com/aws/amazon-q-developer-cli/issues?q=) and there are no duplicates of my issue
- [x] I have run `q doctor` in the affected terminal session
- [x] I have run `q restart` and replicated the issue again

### Operating system

macOS 26.2.0 (25C56)

### Expected behaviour

If my (and Kiro's own!) understanding of subagents is correct, in the How Subagents Work section of the CLI Subagents doc ( https://kiro.dev/docs/cli/chat/subagents/#how-subagents-work ) should not suggest that subagents can pause to request user approval for certain tool permissions, because I don't think the CLI provides support (or at the very least the UX is really bad) for providing approvals to subagents.

### Actual behaviour

When I run a task via a subagent I can see the conversation indicating that the subagent wants approval to do a search but I cannot (via the Kiro/Q CLI interface) provide this approval by entering 'y'. See Steps to repro.

### Steps to reproduce

Prompt:
```
[joshea] > use the default subagent to tell me what the latest breaking news related to Rust-based software development insize Amazon is.
```

```
Invoking subagent: kiro_default with query: What is the latest news about Rust-based software development inside Amazon? Search internal resources for recent Rust projects, announcements, or initiatives. (using tool: subagent)
┌ ! kiro_default: What is the latest news about Rust-based software developme┐
