* Smart objects keep their four-corner (Distort / Perspective) placement

A smart object's placement was an affine transform, so a perspective
placement lost its fourth corner: a mockup PSD's distorted screen looked
right on open (Photoshop's cached pixels) but re-rendered as a
parallelogram after Edit Contents → Save.

- SmartObject gains `perspective`, the full projective map (source px →
  document px); `transform` keeps its affine approximation
- Re-renders go through it (place_source_projective), as do moves,
  canvas rotations and edit.transform, so Distort / Perspective now work
  on smart objects instead of being refused
- PSD import reads the quad (nonAffineTransform / Trnf) and export writes
  it back; .pcraft stores the field (absent for affine placements)
- Test: a distorted smart object survives Edit Contents → Save

* Smart objects: warp maps through a distorted placement; perspective round-trip tests

Warp handles and stored warps on a Distort / Perspective smart object go through its full
projective placement (smart_cmds::placement) instead of the affine approximation, so they sit
on the distorted corners. Tests: SoLd perspective round trip and quad_moved (io), a perspective
smart layer in the .pcraft rich_doc, warp on a distorted smart object (engine). Comments no
longer name another product.
