Allow users to choose between QWERTY and QWERTZ

[Kazuto]

Summary

Aerospace currently uses keybinds optimized for QWERTY keyboards (e.g., alt+[, alt+]). On QWERTZ keyboards (common in Germany, Austria, Switzerland), these special characters are in completely different positions, making the default keybinds awkward or impossible to use efficiently.

Problem

On QWERTZ keyboards:

• Keys like ;require shift+,
• This means alt-shift-semicolon binding becomes alt-shift-shift-,, which doesn't work
• Many special characters like @, ~, {, }, |, \ are in different positions than QWERTY
• The Z and Y keys are swapped
• Umlauts (ä, ö, ü) occupy additional key positions, shifting other characters

This makes the out-of-the-box experience frustrating for QWERTZ users, who need to rebind many keybinds to work with their keyboard layout.

Use Case

As a German user with a QWERTZ keyboard, I want to:

• Use intuitive keybinds that match my physical keyboard layout
• Have a preset configuration optimized for QWERTZ layouts

Current Workaround

Users must manually rebind keybinds in their config file to use keys that are easily accessible on QWERTZ, but this:

• Requires understanding the entire default config
• Takes significant time to set up
• May not be obvious to new users why some keybinds wont work

Additional Context

This affects users in:

• Germany
• Austria
• Switzerland
• Czech Republic
• Hungary
• Other Central European countries using QWERTZ

Given macOS's international user base, having better keyboard layout support would significantly improve accessibility for non-US users.
