[Bug] `/editor` freezes when pasting large amount of text

### 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 15.3.2 (24D81)

### Expected behaviour

Text should be pasted instantly or there's some warning message. At least it shouldn't hang.

### Actual behaviour

Freezes and unresponsive.

### Steps to reproduce

1. Go to https://www.gutenberg.org/files/1342/1342-h/1342-h.htm
2. Copy large amount of text
3. `/editor` and paste

Inizia riproducendo il blocco nel comando `/editor` su macOS con un incolla di grandi dimensioni del testo Gutenberg collegato, dopo aver eseguito `q doctor` e `q restart` come riportato. Traccia la gestione dell'incolla da parte dell'editor e verifica che gli incolla di grandi dimensioni non si blocchino più, non diventino più non responsivi e non terminino senza feedback.
