Group related dialog and inspector settings in reusable frames with optional accessible headings.
Makes the reusable part of [WordCraft #4038](https://github.com/storytold/wordcraft/pull/4038) available to other Craft apps. Includes API documentation, integration guidance and regression coverage. Consumer adoption remains separate; applications retain their themes, localization and command adapters.
Validation on Windows: workspace formatting, strict Clippy and tests; craft-ui Clippy/tests with all features; craft-ui WASM check with all features. Upstream CI results are tracked on this PR.
Includes the shared test-portability prerequisite [#267](https://github.com/storytold/craft-libs/pull/267); the feature itself is independent of the other UI proposals.
[Integration guide](https://github.com/fluorine/craft-libs/blob/fad5c05170d43f9bdf86c6063131e28669fcb176/crates/ui/README.md).

## Summary by CodeRabbit
* **New Features**
* Added customizable sections for grouping content vertically, with optional headings and configurable spacing.
* Sections can fill the available width or use a caller-defined width, and return the result of their content callback.
* **Documentation**
* Added usage guidance and an example for styling sections in dialogs and inspector panels.

* docking: tabs shrink before they overflow
Tabs in a narrow strip shrink, widest first, down to DockStyle::min_tab_width (54 pt at the
default font), cutting their labels with "…" and naming them in a tooltip. Only tabs that do
not fit at that width go to the overflow menu.
* docking: the drag bar narrows once the strip is narrower than the header plus the bar
* craft-ui: match guard for a stack's hit test (clippy 1.95 collapsible_match)
* Update egui to 0.37
egui 0.37 replaces WidgetType with accesskit's Role and renames a few
methods. Mapped per egui's own table (WidgetType docs): Checkbox is
CheckBox, SelectableLabel is Button, Other is Unknown; UiBuilder::id and
Ui::id are scope_id; Id::new is Id::unique (the same hash). No behaviour
change.
egui's test harness now panics on a glyph no installed font has, and its
bundled fonts dropped U+22EE, so the docking fixture's group header draws
an ellipsis instead of a vertical ellipsis.
* craft-ui: README says egui 0.37
