Paths and compound paths now measure their visual bounds along their shape:
the body (inside/outside alignment, the width profile's widest point), the
tips of the miter spikes the limit keeps, projecting caps' corners and the
arrowheads' reach. A rectangle's right-angle miters stay within half the
weight (Fit to Selected Art, Rasterize and all-art SVG export get tighter,
exact boxes); Appearance::outset is the conservative reach for anything else.
Clicks hit what the strokes paint: outside strokes outside the path (0.8 x the
weight out), inside ones inside, the profile's width where clicked, caps,
spikes and heads. Click culling keeps a cheap box (hit test 0.34 ms per click
on the 50k-path budget). The subpath/tangent helpers move from the stroke
geometry into vectorcraft_geom::bez so both share them; a cross-check test
holds every painted point of the real stroke geometry inside the bounds and
hittable.
