* 🐛 Fix stroke to path dropping caps and markers
Caps and markers (round ends, arrows, square/diamond/circle markers) are
painted separately by `handle_stroke_caps` after the stroke itself, so
`stroke_to_path` — which only outlines the shape path — dropped them.
Converting a stroke to a path lost every end decoration except the
Round/Round and Square/Square pairs Skia draws natively, and even those
were missing because the outline paint kept the default butt cap.
Cap geometry now lives in `shapes/stroke_paths.rs` as plain path
builders, shared by the canvas renderer and by `stroke_to_path`, which
unions the caps into the outline for open paths and honors
`to_skia_linecap`. The SVG export no longer overlays the caps a second
time on top of the expanded outline, which would double the alpha of
translucent strokes; the clip silhouette for image strokes gets them
from the outline too.
