The op-* crate reorg never ran `cargo clippy -- -D warnings`, so the CI
lint gate failed. Fix every violation surgically: real fixes for
mechanical lints (needless_range_loop, derivable_impls, ptr_arg,
needless_borrow, doc_lazy_continuation, unused_imports, manual_find,
collapsible_match, never_loop, dead_code, complex types via type
aliases) and scoped `#[allow]` for intrusive ones (too_many_arguments
on paint helpers, result_large_err where ToolOutcome / PenNode payloads
are deliberately the Err type).
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
