Describe the enhancement you want to request

Add Hebrew (he) localization with RTL layout support

opencode currently ships with 17 languages but no Hebrew or RTL support. The app already uses CSS logical properties in many places, so RTL adaptation is feasible.

Would the maintainers be open to a PR adding:

he locale for packages/app, packages/console, packages/ui, packages/desktop(-electron)
Hebrew docs entries under packages/docs/he/
RTL layout fixes (logical CSS props, directional icon flipping, etc.)
If yes, I have a branch ready and will link it after approval.
