📄 Description

Adds recognition for double ESC sequences generated by PuTTY terminal when ALT+arrow keys are pressed (format: ESC ESC [A-D).

Updates the keypress parser to properly identify these sequences and mark them with meta/option flags while ensuring regular arrow keys still work correctly.

Enhances terminal compatibility for users of PuTTY in default mode.
