Guide: the Fillet dialog's Type and Corners in their new words

Curvature continuous is the Type entry's name; Corners (Ball, Smooth patch) and Setback are
described with the command words they write. The codes (G1, G2) stay in the text, where they
explain the words.

`type: "g2"` is an alias. Existing fillets still default to circular, constant-radius G1 blends.
Where three or more rounded edges meet at a corner, the Fillet dialog shows **Corners**: **Ball**
(the default, a piece of the rolling ball's sphere, tangent (G1) to each round) or **Smooth
patch** (`corner: "g2"`: the corner is set back along each edge and filled with a
curvature-continuous (G2) patch, so reflections run through it without a kink). A smooth patch
takes **Constant radius** and **Exact** fit. Its **Setback** is how far along each edge from the
corner the patch starts, one distance for every corner (`setbacks`); left empty, it is 1.5 × the
radius.
Feature references to faces and edges are stored by name, so an upstream edit that moves geometry
keeps them on the right face (see [Persistent naming](../dev/naming.md)). When a reference can't
be found, the feature warns instead of silently picking another face.
