query now emits geometry for Ellipse/Text/MText/Polyline/Insert (on top
of Line/Circle/Arc/Point). Add layers op (name, ACI/RGB colour, on/off,
frozen, locked + current layer) and header op (units, PDMODE/PDSIZE,
LTSCALE, annotation scale, current layer/text style). ocs.py gains
layers()/header(). Lets an agent read the drawing's structure and
settings, not just entity counts.
