vgsp-gr: hold calls on a stream-damaged push so a dropped chunk cannot run LOAD_CONSTANT_BUFFER without its selector state

A chunked GL draw whose earlier chunk was dropped (prelude LOAD-ONLY or the
r1447 arming window hold) replayed the remaining chunks' calls alone; the
constant-buffer selector (0x2380) lived in the dropped chunk, so the bug2548370
macro's LOAD_CONSTANT_BUFFER(0x2390) class-errored (ErrorCode 3) and the
engine poisoned (badf1201 sentinel: pc=513/mac=0xf1 are its artifact, not a
macro). Propagate the stream-relative chunk offset through the candidate and
submit path, keep a per-push STREAM-DAMAGE record of the lowest dropped chunk,
emit later chunks calls-held (the proven-safe shape), never arm the arming
window-hold on a damaged stream, and start a fresh section at stream_rel==0.
r1487: the exact r1485 damaging shape now retires clean (events=5, no poison)
and the next chunk is captured; r1486 (holds off) still poisons because the
first launch runs against a partially packed prelude, confirming the dropped
chunk is the cause, not the hold release.
