feat(cli): enable mouse clicking for cursor positioning in AskUser multi-line answers

[Adib234]

Summary

Enables users to position the cursor using mouse clicks within the multi-line TextInput component, specifically addressing the issue where clicking doesn't work in the AskUser tool when in alternate buffer mode.

Details

• Modified packages/cli/src/ui/components/shared/TextInput.tsx to include a container ref and the useMouseClick hook.
• Added logic to map screen coordinates to logical buffer positions via buffer.moveToVisualPosition.
• Updated unit tests in TextInput.test.tsx to support ConfigContext and mock mouse events.
• Refreshed snapshots for AskUserDialog.test.tsx to reflect visual layout changes.

Related Issues

Fixes #18910

How to Validate

1. Start the CLI in alternate buffer mode: npm run start -- --alternate-buffer
2. Trigger the ask_user tool with a text type question (e.g., "Ask me for a multi-line project description").
3. Type at least 3 lines of text.
4. Click on different lines/columns and verify the cursor jumps to the correct position.

Pre-Merge Checklist

• Added/updated tests
• Validated on required platforms/methods:
  • MacOS
    • npm run

Code Review

This pull request implements mouse click functionality for the TextInput component, allowing users to position the cursor by clicking within the input field when it is focused and the terminal is in alternate buffer mode. The implementation involves adding a container reference to the TextInput's layout and utilizing the useMouseClick hook to trigger buffer cursor movement. Corresponding unit tests were updated to include a ConfigWrapper for context and a new test case verifying the registration of the mouse click handler, alongside necessary snapshot updates. I have no feedback to provide.
