Skip pure-visual leaf includes in the infrastructure pass

Browse Source 
On a million-instance scenery (tomaszewo) the infra pass was spending ~24s
reopening pure-visual leaf twins (grass.incb etc.) just to skip their content --
~200k cParser constructions, because every flora include reopens the same leaf.

Twin header now flags whether a file has any infrastructure node or include
(format bumped to v10). A pure-visual leaf (flora .incb: triangles + transform
directives only) has it clear, so the infra pass skips opening it: the first open
of each file caches the verdict, later opens are dropped before construction.

Result on tomaszewo: infra 55s -> 31s, getToken 1.06M -> 89k. Also adds a load
profiler (per-type build time, dispatch time, getToken count) behind WriteLog so
the next bottleneck is measured, not guessed (it's now the 25s of decorative
vehicle media loading).
