Hi @chrstnb! Thanks for reporting this.

Fixed the RangeError issue. The problem was unbounded shell output accumulation - background shells were appending output without any limit, causing the string to grow indefinitely until it exceeded JavaScript's maximum string length (~1GB).

Solution:

• Added MAX_SHELL_OUTPUT_SIZE limit (10MB) for accumulated shell output
• Truncation logic keeps output under the limit while preserving most recent data
• Prevents the RangeError from occurring

Result:
The CLI no longer crashes after long periods of inactivity. Shell output is automatically truncated at 10MB, keeping the most recent output while preventing unbounded growth.

Opened PR #19716 with the fix. Please review when you have a chance!
