Fix-up in the merge (review): shape.smoothCorners re-smooths a custom outline only when it is a
squircle it drew with the given radius, so a freeform is never replaced by a rectangle.

- #519's handle test iterated the old `ALL` preset list; main has `CATALOG` now.
- The hover hit-test match lists every Hit variant; add #519's Hit::Warp.
- Drop the duplicate "tabs" dialog title that #569 and #637 both added.

A selected text warp shows one yellow handle per adjust.
Dragging it sets that guide value in one undo step.

Shape Format ▸ Text Effects lists the 40 prstTxWarp presets and
No Transform. format.textWarp sets or clears that warp on the
selected text, with optional adjust values.

deckcraft_geom::squircle builds a rectangle outline whose corners start
curving earlier along the edge and keep a shorter circular arc, as design
tools' corner smoothing does. shape.smoothCorners turns rectangles and
rounded rectangles into that outline (custom geometry, so it round-trips
through PPTX), and Edit Shape gains a Smooth Corners slider.

- The magnetic disk's and drum's end ellipses were half the size of
PowerPoint's: ECMA-376 makes them h/6 high (disk) and w/6 across
(drum); measured on PowerPoint's outlines.
- The moon's inner edge was a half ellipse of the box's height; the
standard's is an arc of a larger ellipse through the right corners and
(adj * w, middle) whose centre lies right of that point (radius g18w
across, dy1 down), and so it is fuller. Text rectangle from the standard
too.

Five-, six-, seven- and ten-pointed stars used their own normalisation
and came out narrower or shifted against PowerPoint's. ECMA-376 places a
star's points on an ellipse around (hc, vc * vf) with radii half the box
times hf / vf (star5 1.05146 / 1.10557, star6 1.15470, star7 1.02572 /
1.05210, star10 1.05146), so the points touch the box's edges; now done
for all stars (checked exactly against PowerPoint's outlines at three
sizes and inner-radius adjusts).
Wild synthetic set: star galleries 4.08 -> 3.76, 3.77 -> 3.45,
4.62 -> 4.31 and the adjust galleries slightly.

An outline naming no join was always rounded. PowerPoint rounds most
presets but mitres some by default: classified per preset by comparing
its export (8 pt outline, no join) with round- and miter-joined renders:
the plus, right/up/down block arrows (not the left one), chevrons, stars
from five points up, the equation shapes, curved ribbons and the action
buttons. Miter joins also take PowerPoint's default limit of 8 widths
(kurbo's default was 4), so sharp star points no longer bevel off.
Wild synthetic set: joins slide 0.43 -> 0.21, outline-on-pattern slide
3.95 -> 3.76, preset galleries slightly better.

The sun's rays were thin spikes around a smaller core, and the waves'
curves had the wrong amplitude and shift. They now follow ECMA-376: the
sun's eight triangular rays with bases at the standard's fractions of the
core's margin around a circle of radius 50% - adj (with its handle), and
the waves' cubic edges whose control points sit 10/3 of the amplitude off
the edge, shifted by adj2 (text rectangles too). Checked against
PowerPoint's outlines at three sizes and adjust values (within 0.13 pt).
Wild synthetic set: sun 30 -> 9 per-shape diff; group fill slide (waves)
7.88 -> 5.82; whole set 4.71 -> 4.65.

Plus, minus, multiply, divide, equal and not-equal were approximations
(bars spanning the wrong width, the X's arms too long, the not-equal slash
at the wrong angle and length, dots sized off the shorter side). They now
follow ECMA-376's guide formulas: bars span 73.49% of the width; adjusts
pin as the standard pins them; the X's arms follow the box's diagonals
cut at 51.965%; the slash leans at adj2 through the full height. Each was
checked against PowerPoint's outline at three aspect ratios and custom
adjust values (max deviation 0.002 pt). Text rectangles follow the
standard too.

These presets were hand-drawn approximations and looked visibly different
from PowerPoint's (the lightning bolt had 7 points instead of 11, the
explosions were different polygons, the cloud a ring of lobes without
creases). They now follow ECMA-376's preset geometry, checked against the
outlines PowerPoint gives for them (black-box: merging each preset with a
far-away square and reading the resulting freeform):
- lightningBolt, irregularSeal1/2: the standard's polygons (21600ths);
- heart: its two cubic curves;
- cloud (and cloudCallout's outline): the standard's eleven arcs drawn in
the path's own 43200-unit square, plus the crease arcs, stretched to the
box; arcs take DrawingML's angle convention (direction from the
centre), new Pb::arc_spec;
- flowChartDocument, flowChartMultidocument (three pages, outlined where
they show), flowChartPunchedTape (half-ellipse edges).
Wild synthetic set (per-shape mean diff, 1:1 gallery): lightningBolt
64.1 -> 2.8, irregularSeal1 41.1 -> 5.3, irregularSeal2 41.2 -> 4.8, cloud
28.2 -> 4.0, multidocument 30.9 -> 7.0, punched tape 27.7 -> 4.1, heart
20.9 -> 3.9, document 15.3 -> 3.8. Whole set 5.05 -> 4.84.

- Left/right brackets and braces drew only their curve: a filled bracket
showed no fill. PowerPoint fills them out to the straight side they open
to (the fill path is the curve closed), outlining only the curve.
- Arrowheads were drawn on any shape with nothing filled (brackets among
them) but not on open freeforms that had a fill. PowerPoint puts them on
lines, arcs and open freeforms whether filled or not, never on brackets.
Wild synthetic set: preset galleries 9.44 -> 4.65, 9.55 -> 4.94,
9.60 -> 5.38; extreme-adjust galleries 10.7 -> 6.6.

* Text warps: draw WordArt prstTxWarp presets, round-trip their adjusts
All 40 DrawingML text-warp presets now render instead of drawing flat text.
A warp is a list of bands over the shape's text rectangle (insets ignored):
fill bands stretch the ink of their lines between a top and a bottom guide
(positions by arc length, one horizontal scale for the whole text), follow
bands (arch, circle, button) set lines at natural size along an ellipse arc,
lines stacking outwards on parallel curves, with no wrapping. Lines are
shared over multi-band presets in order (ceil(n/k) per band).
The guide curves were fitted to PowerPoint renders of synthetic decks of
"I" bars (black-box observation, defaults and changed adjusts, 1-3 lines);
most presets match within about a point on a 420 x 200 pt box.
- geom: warp module (guides, presets, band mapping) with unit tests
- render: glyph outlines and underlines flattened, subdivided and mapped
- text: follow warps lay out without wrapping
- model/pptx: BodyProps.warp_adj read from and written to prstTxWarp/avLst

* Text warps: bands with fewer lines keep the fuller band's text height
Multi-band fill warps (Deflate-Inflate, Button Pour) map a box as tall as
the tallest band's ink onto every band, centred on the band's own ink, as
PowerPoint does: a band holding one line next to a band of two keeps the
line at the same size instead of stretching it over the whole band.

* Morph: a changed geometry morphs its outline (a circle turns into a star)
Paired shapes that differ only in geometry (another preset, other adjust
values, a custom path) and fill colour no longer cross-fade: one shape moves
and its outline turns from the old geometry into the new one.
- geom::morph aligns two outlines the way manim does: the same number of
contours, the same number of cubic curves per contour pair, then every
point moves in a straight line. Closed contours are turned and reversed so
the points travel least (a triangle does not twist into a circle), extra
points go to the longest curves, and a sub-path without partner grows out
of (or shrinks into) a point, so a cube's faces appear and a donut's hole
closes. Fill mode, outline and fill rule switch at the midpoint.
- anim::morph_frame lists such shapes in MorphFrame::paths; the renderer
draws them with the morphed geometry (PathMorph, a new render_blend
argument next to TextMorph).
Ported from the path morph in alexplain (MIT, same author).

* Morph: differing looks of an outline cross-fade instead of switching
When a sub-path pair differs in fill mode, outline or fill rule, the two
looks no longer switch at the midpoint. A fill or outline only one side has
fades out (or in), so a filled shape turning into a line loses its fill
gradually. When both fill, the even-odd side lies opaque underneath and the
other fades over it, so a donut's hole fills smoothly while it shrinks.
