Phase 7.3 strangler reorg — rename the native widget host and the desktop runner crates to the op- prefix. The desktop+native merge was declined: keeping the library / binary split preserves the mobile- checkable op-host-native lib (cargo check -p op-host-native on iOS / Android, relied on by check-jian-boundaries.sh + the CI mobile job), which a folded-in winit binary would break. A clean separate rename is purely mechanical and the brief permits it. - openpencil-shell-native -> op-host-native (lib op_host_native) - openpencil-desktop -> op-host-desktop crate; the shipped executable keeps the stable openpencil-desktop [[bin]] name so release artifacts + external CLI integrations are unaffected - every openpencil_shell_core:: path -> op_editor_ui:: - every openpencil_shell_native:: path -> op_host_native:: - doc-comment / manual-smoke note refs updated
