Cursors: 36 more tool states get cursors of their own, listed in cursors.toml

Node editing as the public manual describes it: Direct Selection's anchor squares (hollow
or filled), Reshape Segment over a curved segment, Group Selection's plus (also Direct
Selection with Alt), the arrow hollow while a drag snaps, and Alt-copy arrowheads. The
Anchor Point caret, the Curvature pen and Free Transform's side-shear arrows (ShearH,
ShearV) are drawn in code. Lasso, the freehand, symbolism and other tools return cursors
of their own that borrow their old look until drawn (Cursor::stand_in).

crates/tools/src/cursors.toml lists every Cursor value, when it shows and its hotspot,
for whoever draws them; `cargo xtask cursors` (in ci) warns about a missing, unknown,
repeated or incomplete entry and never fails. The busy cursor is listed as missing (G1).
