Complete the rebrand for surfaces the first pass missed:
- Dev/Nightly/Preview bundle names "Zed Dev/Nightly/Preview" -> "Joule …" (the macOS
menu-bar name for non-stable builds).
- Theme names shown in the picker: fallback theme "Zed Default" -> "Joule Default";
default icon theme "Zed (Default)" -> "Joule (Default)" (const + default.json ref;
registry looks it up by the const, so lookup stays consistent).
- "Update Zed" edit-prediction button -> "Update Joule", pointing at this repo's
releases instead of zed.dev.
- FUNCTIONAL FIX: Linux/Windows keymaps bound F10 to OpenApplicationMenu("Zed"), but
the app menu was renamed to "Joule" — updated the arg so F10 opens the menu again.
Remaining "Zed" strings are all invisible/functional (font aliases, X-Zed-* headers,
bundle/app identifiers, Windows .exe paths, a test fixture) — deliberately kept.
