Hardcraft 0.8.6-alpha.1

Blender add-on for retopology of CAD exports (Plasticity bridge / STEP / OBJ). Working alpha — feed it raw exports only. Docs: https://polozad.github.io/hardcraft-docs/

What's new

• Tessellation is chosen per import. The Import STEP file dialog carries
  a Tessellation preset (Retopo / Bake / Custom) with the Chord
  and Angular numbers behind it; the density an import ran with is
  stamped on the mesh, and Re-import repeats it instead of silently
  changing it. CAD sources.
• Split works on a flat plate with cut-outs — the ordinary split's auto
  chord now stops at the hole rims; before, only the vertex-snapped two-point
  split did anything on a holed plate.
• File → New starts clean. Every session cache resets with the scene, so
  re-importing the same STEP after New no longer sees the closed file's
  state (the Import dialog re-seeds its numbers — the converter used to refuse
  with "invalid parameter value"). Settings are untouched.
• Fix: on commit, the UV seam of a periodic wall (cylinder, revolved skirt) is
  one straight rail — it used to zig-zag across neighbouring edges, worst
  after a section-count tweak.
