Sweep every user-visible product string to Gwen: app menus (Quit, Hide, Gwen Repository), feedback links (repo/issues now point at github.com/kk376/zed, email to yenru@yrkaierx.com), move-to-Applications and update dialogs, provider and settings copy, CLI help, installer and desktop/flatpak/snap/plist metadata. Rename user-facing settings values with back-compat aliases: base_keymap "Gwen" (accepts "Zed"), fonts ".GwenMono"/".GwenSans" (accept ".ZedMono"/".ZedSans"), icon theme "Gwen (Default)". Fix F10 app-menu keymap arguments to "Gwen" and align the Windows installer AppMutex with release_channel::app_identifier(). Internal identifiers, wire protocol names, upstream service URLs and legal attribution are intentionally kept.
