A new 'miter' feature angles a board's end — miter across the width (frame
corners, braces), bevel through the thickness (tilted blade), or both
(compound). Slots into the existing Feature system.
- scene: Feature.miter_deg/bevel_deg; END_KINDS={"miter"}; add_feature forces an
end face and defaults to 45° miter; serialization additive.
- geometry._apply_miter: subtracts a large block rotated about the end (Z=miter,
Y=bevel) so the viewer/export show the real angled end; guarded.
- cut list notes "miter 45° / bevel 15°"; instructions describe the angled end;
jigs suggest a miter sled/gauge for ≥3 repeated angle settings.
- cli feature --miter/--bevel; controller wood-feature passthrough; gen_wood_tools
wood-feature gains --miter/--bevel (re-run it for the voice tools).
- GUI Joinery tab: "+ Miter" button + Miter/Bevel angle fields (live edit/apply).
- tests: default 45°, end-face forcing, JSON roundtrip, cut-list note,
instructions, jig suggestion, and real geometry (volume reduced). 237 pass.
