* Chamfer: refuse a result that grew a convex edge's part (or shrank a concave one's)
A chamfer of a curved edge that runs off a face it skims (robustness seed 57's
ball rim) built a part bigger than before. Checked from the two faces' normals
at the edge; rounds and unclear angles are left to the wedge bound.

* Action matrix: the sheet metal tray's relief corners refuse a 0.25 mm chamfer
Each is a 2.5 mm concave edge (the corner of a corner relief, between two
planes at right angles): a chamfer there fills at most 0.25²/2 × 2.5 = 0.08
mm³. What was built took 0.95 mm³ away; the chamfer guard now refuses it.

* Robustness goldens: seed 57's wrong-way chamfer is now refused (#1390)
On main with #391, seed 57's chamfer grew the part; this refuses it, so the run goes on
to its later steps and ends ok.

A point within the point tolerance of a boundary curve's end is that end in the boolean, whatever its parameter, so text cuts no longer leave unmatched sliver vertices (#391). Robustness goldens re-recorded for seeds 0, 34, 39, 41 and 57 with reasons.
The preview builds only the tool; the boolean runs once on OK, off the window thread, with a Computing label while it takes a while. Follow-up to #1020.
sketch.text and sketch.edit_text make the curve a text follows construction in the same undo step, so it no longer cuts the letters into pieces; the reply names the curve as guide.
A tapered extrude now offsets spline and conic curves as well as lines and arcs, so sketch text and any other profile can take a taper, and the join of tapered letters onto a face finds its boolean result.
The live preview of a join, cut or intersect now sends the tool body's scene as soon as the tool is built, then runs the feature for its error while the dialog keeps its spinner. OK pressed while the preview is still computing the same commands waits for it instead of computing the feature a second time on the UI thread; the session shares its evaluation cache with the preview's scratch copy.
A sketch text gets an optional style: bold and italic faces (a slanted fallback for italic), left/center/right alignment, letter and line spacing, and a path curve of the same sketch for the baseline to follow (reverse takes the other side). Edit Text gets B/I toggles, alignment, spacing fields and a Path chip, all live. The style is saved only when not plain and is noted under format 18.
When an extrude cuts with profiles whose outlines stay more than 1 µm apart (the letters of a text), their tools are apart too, so they are joined and cut from the body in one boolean instead of one per profile. A ten-letter text cut drops from about 13 s to 1.5 s with the same result. Sheet metal targets and touching profiles keep cutting tool by tool. Tapered extrudes are unaffected.
