Keybind Ctrl + . does not work with non-US keyboard layouts (e.g., Russian)

Description

The Ctrl + . keybind is matched against the produced character of the pressed key rather than its physical position. On non-US layouts the period character lives on a different physical key, so the shortcut requires pressing a key the user is not used to.

Concretely with the Russian (ЙЦУКЕН) layout:

• The physical period key (US key code 190) types ю on the Russian layout, so Ctrl + 190 does nothing.
• The period character . is produced by the physical key with code 191, so the keybind only fires with Ctrl + 191.

Plugins

OpenCode version

Steps to reproduce

1. Switch the keyboard layout to Russian (ЙЦУКЕН).
2. Press Ctrl + . on the physical period key (US key code 190).
3. The keybind does not fire.
4. Press Ctrl + 191 (the key that types . on the Russian layout).
5. The keybind fires.

Additional context

Expected behavior: keybinds should be layout-independent and bind to the physical key position (e.g., e.code === "Period" for key code 190) instead of the produced character (e.key). With the current behavior the same physical key triggers different keybinds depending on the active layout, which is confusing when switching between layouts.
