The DtoH staging buffer lives in the client's high-VA /dev/zero|nvidia
mappings (e.g. devptr+0x3c00100), outside the scanner's fixed CE/GR
windows; only the host's pagemap read can see it. The guest scanner
now walks those VMAs and streams their present pages so the module
pins them. run_cycle.sh learns the sema_dbg master switch (auto-on
when any watch knob is set).

payload-pattern audit
- CE LAUNCH_DMA releases are now applied after the push's collected work
runs: the client reads copied data as soon as it observes the release,
so release-first let cuMemcpyDtoH observe a copy that had not executed.
- Unreadable CE entries stay pending for a grace window (sema_ce_grace_ms,
default 8s) before the release fallback consumes them, so a translation
that lands within a service pass lets the push be decoded and its work
executed instead of being dropped.
- sema_copy_pat matches an 8-byte value against every copy's src/dst first
word and scans decoded pushes for it, naming the submission that carries
a known payload regardless of size/encoding.
- sema-dma-skip logs transfer-shaped launches that collect no op; op log
lines carry the channel handle; LAUNCH_DMA inventory follows OPS_LOG.
- A real release application now records the release VA, so decoded pushes
no longer trigger a spurious fake release.
