M11: widgets draw lines and SVG pictures (plugin API 6) (#1727)

A widget description can have a line, 100 long and black and 1 thick unless told
otherwise, and an SVG that comes in as locked layers, scaled to fit a size and
within the widget's 256 layers. The Counter example uses both.

| 2026-10-31 | minor | M11, gap 6: widgets draw lines and SVG pictures, as a Figma widget's `Line` and `SVG` do (plugin API 6; older plugins unchanged). A line is 100 long, black and 1 thick unless told otherwise, and turns around its top-left corner. An SVG comes in as locked layers, scaled to fit a size, within the widget's 256 layers. The Counter example uses both. Numbers unchanged. Tests: `widget_shapes_tests`, `widget_tests`. |
| 2026-10-31 | patch | M12, #1708: a connector end dropped on the outer half of a shape takes the side it is towards, instead of only within 10 px of a side's middle, so a drop anywhere along an edge chooses that edge (dragging a selected connector's end and with the connector tool, ring included); a drop in the middle of a shape still takes the facing side. |
| 2026-10-31 | minor | M8, #1351 and #1124: both reports checked by running them and already fixed on main, so only tests are added: a rounded rectangle or frame strokes only the side asked for, in every alignment (`a_rounded_shape_strokes_only_the_side_asked_for`); a font family and a layer name written as an id drop characters XML forbids (`ids_and_font_families_drop_xml_forbidden_control_characters`). No behaviour changes. Numbers unchanged |
| 2026-10-31 | patch | M8, #1474: an image whose header reads but whose pixels don't is refused with a reason when placed, used as a fill, pasted or opened, instead of going in as an empty box with nothing said. A file that won't open at launch now says so in the window. |

A widget removed meanwhile isn't redrawn (the callback rolls back, the panel stays); an API 3 or 4 plugin's `ui_show` from a widget still opens nothing; a presented prototype opens no panel.

Where the browser lists them (Chromium's Local Font Access, `window.queryLocalFonts`), the Design panel's font menu offers "Use fonts installed on this computer…"; the browser asks for permission, and the fonts join the font list by name, with their styles. A font's bytes are read only when text uses it, one style at a time (its preview in the menu waits until then), and auto-sizing text fits it once it is in; one that can't be read is dropped and its text keeps the fallback. A family the build embeds keeps its faces; the computer's styles it lacks join it. Other browsers show no row (`figcraft_text::add_local_fonts`, `apps/figcraft-web/src/local_fonts.rs`).
