Felipe Coury fe0d472c4c Adapt keyboard event reporting to the terminal (#35021 )

## Why

Reporting key event types can leak an exit-shortcut release into the parent
shell in iTerm2 and can cause tmux's `xterm` extended-key format to lose
Shift+Enter.

## What changed

- Select keyboard enhancement flags using the detected terminal and tmux
  extended-key format.
- Disable event-type reporting for iTerm2 and tmux's `xterm` format while
  retaining alternate-key reporting.
- Preserve event-type reporting for other terminals and tmux's `csi-u`
  format so repeat events remain distinguishable.

## Testing

Added unit coverage for iTerm2, Kitty, unknown terminals, and both tmux
extended-key formats.
