  1. tui: Only query keyboard enhancement support once 

    We query the host terminal emulator to check whether it supports the
keyboard enhancement protocol after entering raw mode on startup. We
only need to check this value once though, so we can store the result
in a OnceCell to prevent repeated queries. The query for keyboard
enhancement support times out and fails when suspending (C-z) and
resuming (`fg`) which can cause delays and leaves sequences in the
terminal after Helix suspends or exits. Caching in the OnceCell
prevents this behavior.
