Reported on #1178: with "route": "avoid", two contacts one above the
other, wired bottom terminal to top terminal 30 px apart or closer, got
a five-segment loop (at 20 px: v 80, h -20, v -140, h 20, v 80) that ran
down through the lower contact and back up past the upper one.
The cause was exitPoint(): it walked out of a terminal until clear of
every obstacle, so with another symbol in front it walked through that
symbol, and the search then had to come back. The same walk made a wire
between two symbols inside a frame (a cabinet drawn as one element)
leave through the frame's side, go round, and cross back in.
The router now knows each terminal's own symbol (Request::start_symbol,
end_symbol; applyRoute() fills them):
- two terminals facing each other on one line with nothing between
them are joined straight, however close;
- the exit walks through the margin around other symbols but never
through one; a terminal pointing straight into another symbol gets
"no-route" instead of a route through it;
- an obstacle drawn around either end's own symbol is left out.
Without the symbols (the old Request), routes are as before.
Rerouting every wire of four shipped examples (perceuse, affuteuse_250h,
Polonez, industrial; 1331 wires): master routes 121 of them through
another symbol, this none (10 pass through a second symbol lying
exactly on an end symbol's rectangle, which no route can avoid). 99
wires that master routed through a symbol now get "no-route" and keep
their path. The 1232 wires both route are 6 % shorter in total
(436,144 -> 410,608 units) with 11 % fewer bends (2256 -> 2010).

A new conductor gets the default two or three straight segments, which
run through whatever symbol or wire lies between its terminals; scripts
then fix it segment by segment with moveConductorSegment().
ConductorRouter finds an orthogonal path on the folio grid that leaves
and enters each terminal in its own direction, keeps clear of every
element's rectangle, stays inside the border, and charges for bends and
for running along or crossing other wires. qet.routeConductor() and
qet.routeConductorBetween() apply it through Conductor::setPathPoints(),
which pushes the same ChangeConductorCommand a handle drag does, so the
path is saved, survives a reload, and one undo restores the default.
Where no route exists the wire keeps its path and the call says so.
qet-mcp: add_conductor takes "route": "avoid", and a route_conductor op
reroutes an existing conductor (by terminal or by uuid). The router
methods are required only by an edit that routes.
