fix(android): send Ctrl for the command modifier so cmd+a selects all

[mobile-kevin]

Problem

io keys documents cmd+a as select-all, but on Android the "command" modifier mapped to KEYCODE_META_LEFT. Meta+A opens the Google Assistant instead of selecting text, so cmd+a/cmd+c/cmd+v all did the wrong thing and yanked the app out of the foreground.

Fix

Android's primary shortcut modifier is Control, so map the canonical "command" modifier to KEYCODE_CTRL_LEFT. iOS still maps it to the Command key, where cmd+a already selects all. (cmd, command and meta all normalize to "command" upstream, so they now all send Ctrl on Android — matching the documented select-all semantics.)

Tests

• Unit: command and control both map to KEYCODE_CTRL_LEFT, and command must not map to Meta.
• Verified live on the emulator: typed text into a field, cmd+a + backspace cleared it, and the foreground stayed on the app (the Assistant no longer opened).

Summary by CodeRabbit

• Bug Fixes
  • On Android, shortcuts using the Command modifier now map to the Control key, rather than the Meta key. This aligns Command shortcut behavior with the cross-platform mapping and helps shortcuts using Command work as expected on Android.
