feat(bundle): add platform-adaptive file, find and comment shortcuts

New, Open, Save and Find are Monaco KeyMod.CtrlCmd bindings matched
with StandardKeyboardEvent, so they use Cmd on macOS and Ctrl on Windows
and Linux, exactly like the editor's own keybindings. Find also works
from Input and Output by focusing the editor first. Toggle Line Comment
comes from Monaco's comment contribution and the plugin's "//"
lineComment. This replaces the Save handler that accepted Ctrl or Cmd
with any other modifiers on every platform.
