feat(tui): add option to toggle displaying terminal title

[jknlsn]

Adds tui.set_terminal_title config option to complement the existing OPENCODE_DISABLE_TERMINAL_TITLE env flag.

Usage:

{
  "tui": {
    "set_terminal_title": false
  }
}

Does it have to be config? Rather than just adding ctrl+p -> toggle title option that's persisted to the kv?

(in the tui code)

No, it doesn't have to be. I've just implemented as a toggle title option that's persisted to the KV now.
In general are you thinking that TUI options should be implemented this way rather than config, or case by case?

Primarily case by case I think, it just depends, im not entirely sure if we like the tui in the config given the multiple clients but idk i think it's there to stay
