v1.4.1

Release 1.4.1

Atlas bake: zero bake margin -- the rig's per-pixel UV islands touch with no
gap, so any margin dilated each island's edge into pixels its neighbour owns
(e.g. the dark sleeve-bottom band over the arm-front's last row). Drop the
unused atlas blur path (a dead-end fix attempt). Viewer-side, the web tool
now clamps light-atlas samples to their own 1/64 skin-pixel cell instead.

UI: the Animation tab is stable since 1.4 -- always show it (drop the
"Enable animated export" add-on preference).
