Contextual Task Bar: the Type tools show font family, style, size and Fill

While a Type tool (Type, Area Type, Type on a Path and their vertical
versions) adds or edits type, the task bar shows the font family and
style menus, the Font Size combo and the Fill chip. Type selected with a
selection tool shows the same font controls beside its Create Outlines,
conversion and Type on a Path items. The controls change what the
Character panel's would: the selected characters, else every selected
type object. The Touch Type tool still shows no bar.

While a Type tool edits type, the Fill chip shows the selected
characters' fill, with "?" where their fills differ. On a canvas too
narrow for one row, the font controls go on a second row and narrow to
fit. Screen readers name each control.

   - Window › SVG Interactivity attaches JavaScript to the selected objects' events (`onclick`, `onmouseover` and 17 more) and links JavaScript files to the document (Link JavaScript Files…); SVG export writes the events as event attributes and the files as `<script xlink:href>`, SVG import reads both back as text without running them, and the native format keeps them (`svgInteractivity.*`).
   - Numeric fields keep the pointer's pressed character as the text-drag start when movement exceeds the click threshold (#1326); a completed focus click selects the unit too. Pixel/point, plain and optional fields are regression-tested in both directions, before/after focus, with replacement text; keyboard focus, double-click, arrows and wheel keep their prior behavior. Native egui input confirms partial replacement gives 17 px instead of 700 px, one Undo/Redo, window captures and an exact saved-document read in a separate CLI process. A focus click released more than 1 pt from its press keeps the caret, and a tap within 1 pt still selects all (#6659; short-drag and jitter-tap regressions in `tests/numfields.rs`).
   - Unit fields and length strings take `%` in arithmetic: `3cm*50%` reads as 1.5 cm, and `50pt+25%` reads as 62.5 pt.
-  - The contextual task bar's handle drags it anywhere on the canvas (kept whole on it as the window resizes); unpinned it keeps that offset as it follows the selection, and its More Options menu hides it, pins its position across selection changes (`window.taskBar.pin`), resets it under the selection (`window.taskBar.reset`) and shows the Properties panel. As in Illustrator the position isn't kept across launches. Not done: the bar's variants for other tools (only the selection tools and the Artboard tool show it).

   - A click on another object moves the contextual task bar under it without hiding it for the press; it gives way only to a drag (#4681).
   - With one image selected, the contextual task bar offers Image Trace, which traces the image at once with the Default preset (the Image Trace panel is left as it was), and Crop Image; with an Image Trace object it offers Expand, which keeps only the traced paths. This follows Illustrator's bar: for a selected image it includes Image Trace, Retype and Crop Image, and traced artwork can be expanded from it ([Contextual Task Bar announcement](https://community.adobe.com/announcements-651/contextual-task-bar-in-illustrator-2025-quick-actions-when-you-need-them-1546580)). Offset Path and Simplify, which don't apply to an image, aren't offered for one. Not done: Retype, which the app doesn't have.
   - With the Artboard tool, the contextual task bar sits under the selected artboards and offers Resize (Artboard Options for the active artboard), Duplicate (each selected artboard, in one undo step, the copies then selected), Rearrange All (with two or more artboards) and Export (Export for Screens with the selected artboards checked). This follows Illustrator's bar: while the Artboard tool is in use, it has options for resizing, duplicating and exporting artboards (the [Contextual Task Bar announcement](https://community.adobe.com/questions-652/contextual-task-bar-in-illustrator-2025-quick-actions-when-you-need-them-1546580); Rearrange and Export on the bar: [Managing Artboards in Illustrator](https://creativepro.com/managing-artboards-in-illustrator/)).
   - The contextual task bar offers more next steps by selection (<https://helpx.adobe.com/illustrator/desktop/get-started/learn-the-basics/contextual-task-bar-overview.html>): an open path Join and Edit Path (the Direct Selection tool), a closed path Edit Path, a compound path Edit Path and Release Compound Path, a clipping group Edit Clipping Path and Release Clipping Mask instead of Ungroup and Isolate, an image selected with vector art Make Clipping Mask instead of Unite, point or area type Convert To Area Type or Convert To Point Type beside Create Outlines, and type on a path, for which the overview names an item to add an effect and rearrange the text, Type on a Path Options (`type.pathOptions`; its options: <https://helpx.adobe.com/illustrator/using/creating-type-path.html>) beside Create Outlines. Evidence: `crates/ui-egui/src/tests/taskbar.rs`.
+  - While a Type tool (Type, Area Type, Type on a Path and their vertical versions) adds or edits type, the contextual task bar shows the font family menu, the font style menu, the Font Size combo and the Fill chip (<https://helpx.adobe.com/illustrator/desktop/get-started/learn-the-basics/contextual-task-bar-overview.html>); the Touch Type tool shows no bar, as the same page describes. Type selected with a selection tool shows the same three font controls beside its Create Outlines, conversion and Type on a Path items (<https://helpx.adobe.com/illustrator/desktop/design-with-text/fonts-and-scripts/font-options-overview.html>). The controls act as the Character panel's do: on the characters a Type tool selects, else on every selected type object, with the size left blank where the sizes differ. VectorCraft's own rules: a Type tool's bar leaves out the object actions, the Stroke chip, Recolor Artwork and Lock; a Type tool shows no bar before it adds type or with other art selected; type selected with other art shows no font controls; the font controls go on a second row when one row would be wider than the canvas, and narrow to fit a canvas narrower than they are; while a Type tool edits type, the Fill chip shows the edited characters' fill ("?" where it differs). Evidence: `the_type_tools_show_font_and_fill_controls`, `the_type_tools_show_no_bar_without_type`, `selected_type_shows_font_controls_beside_its_actions`, `the_task_bars_font_size_sets_what_the_character_panel_would`, `the_type_tools_fill_chip_activates_the_fill`, `the_type_tools_bar_is_named_and_stays_on_the_canvas`, `selected_types_font_controls_take_a_second_row_on_a_narrow_canvas` and `the_type_tools_fill_chip_shows_the_edited_characters_fill` in `crates/ui-egui/src/tests/taskbar.rs`.
   - With a live rectangle, rounded rectangle, ellipse or polygon selected with the Selection tool, the contextual task bar shows a Shape Properties button in place of Lock. It opens a popup with the shape's rows from the Transform panel (corner radius, pie angles, or sides, angle, corner and radius), which edit it through `object.setLiveShape`. The overview describes this: when a shape drawn with a shape tool (Rectangle, Star) is selected, the bar offers to change its properties where Lock Object would be ([Contextual Task Bar overview](https://helpx.adobe.com/illustrator/desktop/get-started/learn-the-basics/contextual-task-bar-overview.html)). Object › Lock and ⌘2 still lock the shape. Not done: stars, which the app draws as plain paths. Evidence: `a_basic_shape_shows_its_properties_in_place_of_lock`, `the_shape_properties_popup_edits_the_shape` and `other_selections_keep_lock` in `crates/ui-egui/src/tests/taskbar.rs`.
   - The contextual task bar has a Stroke chip beside the Fill chip, drawn with the paint the Stroke proxy shows (a "?" when the selected objects' strokes differ, as on the Fill chip); a click brings the Stroke proxy forward and shows the Swatches panel wherever it is docked, floating or closed, as a click on the Fill chip does for the Fill proxy. The reference app's bar has Fill and Stroke controls for changing an object's colors ([Contextual Task Bar overview](https://helpx.adobe.com/illustrator/desktop/get-started/learn-the-basics/contextual-task-bar-overview.html)). Evidence: `the_task_bar_shows_a_stroke_chip_beside_fill` and `the_task_bar_chips_follow_the_proxies_and_show_swatches_anywhere` in `crates/ui-egui/src/canvas/tests.rs`.
   - With anchor points selected with Direct Selection, the contextual task bar offers Remove Anchor Points, Connect (`path.join`), Cut Path, Corner and Smooth (`path.convertAnchors` with `to` set to `corner` or `smooth`), the commands of the Control bar's anchor buttons. As in Illustrator, whose bar has items that delete the selected anchors, join selected end points, split the path at the selected anchors, and make the selected anchors corner or smooth points ([Contextual Task Bar overview](https://helpx.adobe.com/illustrator/desktop/get-started/learn-the-basics/contextual-task-bar-overview.html)). Not done: Simplify, which the bar offers only while no anchors are selected, and the bar's Smooth item that adjusts a path's curvature, a command the app doesn't have (Object › Path › Smooth).
