* Vector: bound flattening memory, keep over-budget dashes, cheaper edge build (#5195)
- flatten: a path's flattened points are capped at 1 << 20; past it every
curve keeps a proportional share of its pieces (at least one), so hostile
handles from files (vmsk, SVG, effect outlines) cannot exhaust memory.
fill_rasterizer flattens the whole path under one budget.
- stroke: past the dash step budget (or below coordinate precision),
dash_polyline keeps the dashes made so far and draws the rest solid
instead of dropping the stroke. Open polylines are no longer copied.
- raster: coordinates are clamped to +-1e15 and edges with a non-finite
slope (vanishingly short) are skipped, so huge finite coordinates no
longer produce NaN coverage. fill_rasterizer sorts edges once instead of
after every component (stable sort, identical order).
- Cleanups: dead miter `half`, dead loop-length check in trace_mask,
shared mask render body, map_knots helper, shared straight-segment test.

* Vector: bound stroke outline points (#5211)
- stroke_polygons dashes all lines first, then counts round caps and
joins. When their full-resolution tessellation would exceed 1 << 20
outline points, every round cap and join gets the same smaller segment
count (down to 4 per circle, 1 per join; area-exact radius kept).
Strokes under the budget are unchanged; no piece is dropped.
- The dash step budget (100000) is now shared by all lines of a stroke
instead of per polyline, so many subpaths cannot multiply the dash
(and cap) count. Past it the rest is drawn solid, as before.

Edit › Transform › Distort / Perspective and Warp on a shape layer let the
user edit the box or mesh and then refused at commit ("needs a rasterized
shape"). Photoshop maps the shape's path and keeps it a shape.
- photocraft-vector: new `map` module. `map_points` sends every anchor and
control point through a map (Distort / Perspective: exact for straight
segments, exact end tangents for curves). `map_path` follows a curved map
(Warp), halving each segment until the mapped control points follow the
mapped curve within a tolerance (at most 64 pieces a segment, bounded in
total); straight segments whose image is straight stay straight.
- engine: `transform_layer` and `warp_layer` map a shape's path instead of
refusing; a live rectangle/ellipse/polygon/line becomes a plain path. A
linked vector mask now follows Distort / Perspective / Warp too. A map that
sends a point to infinity is an error, not a corrupt path.
