Fillets and chamfers meeting at corners on curved faces: what #935 leaves (#854)

Browse Source 
* Fillets and chamfers meeting at corners on curved faces, on top of #935

What #935 and #926 leave of #851 and the matrix:

- Corner build for blends meeting on faces of any surface (curvecorner.rs):
  the knife-edge tip's round with the arc's or the back edge's, edges
  picked in any order, a round ending in an earlier round of its radius
  (as a feature of its own), and chamfers meeting at the arc's corner.
  Its end curves are fitted by chord length: a uniform parameter
  through points clustered at the ends doubled back on itself there,
  and the display planner refused the face.
- A straight edge ending at a curved face (the back edge into the
  knife-edge tip): rolled, or cut by the face in the planar corner
  build (blend_corner.rs).
- A rolling ball turning about a rounded corner of its own radius
  (a pivot: a piece of sphere or cone).
- Seams that are an earlier blend's straight contact (fitted curves)
  count as straight.
- No spline across a joint where the strip's curvature jumps (a line
  into a small round): each strip ends on the joint's section.
- Sections at a chain's vertices on the faces of the edge from it
  alone.
- Every new fillet path passes #949's check for openings.

Tests measure volumes through the display plan, as #935's do.
Action matrix: 51 more fillets and chamfers pass (sweep, tangent arc
chain, sheet-metal hem, bracket holes), none fewer. Robustness seed 33
recorded (its last fillet builds differently; display and measured
volumes now agree).

* Corner blend tests: scale, seed 33's volumes, tighter engine bounds

From the review of #854:

- seed_33_display_plan_and_measure_agree: seed 33's bodies measure
  the same through the display plan and the measure (2e-5), which the
  golden's re-record rests on.
- the_arc_rounded_after_the_back_edge_matches_both_together: the order
  that still leaves 0.05 mm³ at the tip, as an ignored test.
- corner_blends_hold_at_any_scale: the cases this branch adds on the
  #851 part, at 0.01x and 100x, take off what they take at full size
  times k³ (within 5e-6, checked to 1e-4).
- The engine tests on the part as drawn measure through the display
  plan; bounds are about twice what each reads (2e-4 to 3e-3), and the
  front corner's sets are checked against the kernel's CSG grid.
