hermes - 💡(How to fix) Fix [Bug]: Desktop app freezes when pasting large multi-line text into composer [1 pull requests]

Bug Description

In the Hermes Desktop app, pasting a large multi-line text (e.g., a full log file copied from a terminal) into the chat composer causes the entire application to freeze / become unresponsive.

The paste action itself triggers the hang — the app does not recover and must be force-quit.

Steps to Reproduce

1. Open Hermes Desktop app.
2. Copy a large block of multi-line text (e.g., a full log file from ~/.hermes/logs/desktop.log with thousands of lines).
3. Paste the text into the chat composer / input box.
4. Observe that the app freezes immediately and becomes unresponsive.

Expected Behavior

The composer should accept the pasted text, or at least handle it gracefully (e.g., truncate, warn, or debounce) without crashing the entire application.

Actual Behavior

The Hermes Desktop app freezes immediately upon pasting the large text. The UI becomes completely unresponsive and requires a force-quit.
