*	tools: inject_counters.sh - counter index order is descending by handle	Arthur Hanson Rasmusson	2026-09-29
\| \| \| \| \| \| \| \|	Live verification: the trackers waiting on counter slots idx2/idx3 belong to the channels 2nd/3rd from the top of the ascending handle list, and the only channel whose GPFIFO put advanced to 2 was the 4th from the top, whose tracker polled idx3. Zip descending handles with ascending counter indices by default; ORDER=asc restores creation order.
*	tools: durable guest counter enumeration/injection and VA reader	Arthur Hanson Rasmusson	2026-09-29
	The counter enumeration/injection workflow lived in the guest's /tmp and was lost on every restart. Make it durable under tools/guest-diag: - sem_counters.py: translate a process's per-channel u32 completion counters (16-byte stride in the /dev/nvidiactl counter page) to guest PAs through /proc/<pid>/pagemap; --pairs emits handle,va,pa triples. - sem_slots.py: read/write the counter slots via /proc/<pid>/mem (fallback for the host counter publish). - read_va.py: hex dump a process VA (UVM sysmem GPU VAs are usually valid CPU VAs in the owning process); --u32 for method streams. - inject_counters.sh: host-side one-shot: push the tool, take the GR handles from the live chan_dump, enumerate, then register each counter with sema_counter and pin its VA with sema_map_add. - push_guest_tools.sh: push the new tools after every VM start. - launch_qemu_direct.sh: parameterized mdev UUID/paths instead of a stale hardcoded one; committed so it survives checkouts.
