TheRON dfd02a4fd8 geom: port the pure-geometry half of sb-geom 
Vectors, GEO and MEMBER records, member placement, sleeve and cavity
paths, exact polyline distance, corner-radius derivation, and the
monotone solver. Direct translation of legacy/openscad/lib/sb-geom.scad
at rev 8.0.0.

Angles stay in degrees, matching OpenSCAD, so every expression reads the
same as its source line. The 44 solver iterations, the 0.999 and 0.98
scale factors, the 0.05/179.95 cutoffs and the 1e9 sentinel are
reproduced exactly: they shaped the frozen oracle.

Region operations are not included -- they need a 2D boolean kernel and
follow with the Shapely layer.

49 unit tests, none of which touch the oracle. Harness proven by
mutation: radians for degrees, a shortened solver, a dropped scale
factor, a skipped crossing test and a flipped offset sign are each
caught. Oracle acceptance still skips; 236 unchanged.

TheRON b67cc1290e verify.sh: reach the restore on the diff branch 
set -euo pipefail aborted the script on the diff pipeline one line
before the cp that restores the pre-run oracle, so --full left a
regenerated fixture file in the working tree while printing that
nothing had been overwritten. Appended || true.

Recorded as F-033. The fix is not yet exercised: the restore branch
runs only under --full and has not been entered since the change.
