Introduces wire.breakout: a 45° diagonal line of configurable length
(default 1em) that starts at a given (x, y) and exposes a port anchor
<id>-port-<id> at its end point so wires can attach to it as if it were
a block port. A synthesized <id>.center anchor is placed opposite the
configured port-side so the side the port faces can be deduced from
the anchor.
- x/y accept number, (rel:, to:) and (from:) forms; (from:) sets the
start point to the referenced anchor's coordinate.
- direction: one of north-east/north-west/south-east/south-west.
- Optional label positioned via name-pos (NE/NW/SE/SW); when name-pos is
opposite to direction, the label falls back to the start point so it
never covers the diagonal line. Label padding matches wire.wire (3pt).
Also adds three examples (breakout, breakout-label, breakout-wire) in
doc/examples.typ referenced from the docstring so tidy auto-renders
them in the manual, and a gallery entry (gallery/test_breakout.typ)
demonstrating orthogonal bus fan-out with breakouts in all four
directions.
CeTZ 0.5.2 requires 3D coordinate vectors (x, y, z) for raw
coordinate tuples passed to coordinate.resolve(). Update internal
wire computations (dodge, guided) to use 3-element tuples, fix
.last() to .at(1) for y-component access on resolved coordinates,
and add a normalize-coord utility that automatically pads user-
provided 2D points (x, y) to (x, y, 0) so users do not need to
specify the z dimension.
