Phase 7.3 strangler reorg — the final consumer (op-pen-loader) is
repointed off the openpencil-shell-core shim onto op-editor-ui (the
real source crate for the layout scene / scene-var / render-backend
facade), then the shim crate is deleted.
- op-pen-loader: openpencil-shell-core dep -> op-editor-ui;
every openpencil_shell_core:: path -> op_editor_ui::
- git rm crates/openpencil-shell-core/ (lib + jian.rs module + the
two re-export anchor tests, all superseded by op-editor-ui's own
surface; the jian.rs module had no consumers outside the shim)
- stale shell-core / shell-native comment refs in op-editor-core +
op-host-desktop manifests updated
Three additive variable-handling fixes so the editor host can migrate
onto EditorState as a mechanical port:
- Gap 1: add `variable: Option<String>` to ColorPickerState, port
`open_color_picker_for_variable`, and route `color_picker_set_hsv` /
`close_color_picker` through `set_variable_color` when set.
- Gap 2: add `op_pen_loader::editor_state_var_table(&EditorState)`,
folding persisted variables/themes plus the transient active-theme
selection + ref caches into a shell-core VariableTable. Lives in
op-pen-loader (not op-editor-core) to keep op-editor-core wasm-clean
and free of any shell-core dependency.
- Gap 3: confirmed undo/redo of variable create/delete/rename round-
trips for free (EditorSnapshot clones the whole PenDocument); added
tests to lock it in.
