- Miter gains a from_center option: pivot at the end CENTRE so it notches a
corner instead of cutting full width. Add a +angle and a −angle from centre on
the same end to bring it to a point (picket fence). Feature.from_center;
geometry.miter_cutter honours it; Joinery panel checkbox (miter only); CLI
feature --miter-pivot edge|center; wood-feature tool arg; serialization.
- Chamfer preview now shows the actual bevel slivers it removes (board −
chamfered board), like the miter wedge — instead of a flat face slab.
_chamfer_removed_mesh, with the face-highlight as fallback.
- tests: center miter notches a corner, two center miters make a point,
from_center roundtrip, chamfer preview is real geometry. 247 pass.
Re-run gen_wood_tools.py for the voice tool to expose --miter-pivot.
