fix(terminal): swallow Ctrl+Z in agent sessions so it cannot suspend a running CLI
Ctrl+Z raises SIGTSTP on the pane's tty. In a shell session that is ordinary job control and
is left alone, but in an agent session suspending the CLI stops an unattended loop dead with no
visible output, the same failure shape as an XOFF freeze. The key is now swallowed in
attachCustomKeyEventHandler for every non-shell mode, and unconditionally in the
subagent/teammate terminals, which always run an agent CLI. The match is case-insensitive,
because Caps Lock flips ev.key to 'Z' without setting shiftKey and a plain === 'z'
check would let exactly the keystroke this exists to catch through.
This is defence in depth rather than a fix for the steady state: an agent CLI holds its tty in
raw mode with ISIG off, where ^Z is already inert. It covers the moments that are not the
steady state: the window before the CLI takes the tty at startup, and any point where it hands
the tty back. Two input paths are deliberately not covered and still reach the PTY: the mobile
keyboard accessory bar's one-shot Ctrl, and the CJK composition textarea when cjkInputEnabled
is on. Both are separate choke points to the PTY, and both are worth covering if this ever
turns out to matter in practice.
