Hardcraft 0.8.7-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

• Core span on Alt+Wheel. In CURVE, select the two curves to reduce and
  wheel: the interior tube's span reads as core N on the pair, starts at
  the pair's own span, only goes down, and fills plain again at the top. The
  core belongs to the pair — the other pair, Clear, or F start it over.
  CURVE.
• Problems are said where you look. A refused gesture (no curve selected,
  contour on a cut, core span on the wrong selection or on unequal caps) shows
  as a coloured line in the HUD block on the left for a few seconds; the
  status bar still logs it.
• Fix: weld preview showed the mirrored ghost as tint only — its wire is back
  at any distance, and it no longer shows through the part. The
  SYM_WIRE_CAP_FRAC setting is gone (a stale key in settings.json is
  ignored).
• Fix: two identical curves contoured by different amounts under Ctrl+Wheel —
  the contour no longer depends on how the CAD tessellated the curve.
• Fix: turning the Core span knob in the redo popup could crash Blender.
• Fix: Core span on unequal caps used to do nothing silently; it now refuses
  and says why.
