[Bug] ANSI escape sequences bleeding into the terminal stdout

[nxtcoder17]

After program finishes, the gibberish text appears on stdout, sometimes before the prompt also

The garbage text 11;rgb:1f1f/1f1f/2828;1R11;rgb:1f1f/1f1f/2828;1R is a terminal response leak. Here's what's happening:

1. Something in the run tool (likely a TUI library like lipgloss/charmbracelet) sends an OSC 11 query (\e]11;?\a) to detect the terminal's background color
   (dark/light mode detection)
2. The terminal responds by writing 11;rgb:1f1f/1f1f/2828 back to stdin
3. The ;1R is a cursor position report (DSR/CPR response)
4. By the time the terminal responds, the querying program has already exited, so the response gets dumped as raw text on the prompt

This is a well-known race condition with terminal query sequences.
