*	spdx: add BSD-3-Clause identifiers to userspace/tools/scripts sources	Arthur Hanson Rasmusson	4 days
\| \| \| \| \| \| \| \| \| \| \|	Sweep of the 155 tracked C/Python/shell files under userspace/ (excluding the MIT-licensed vendored userspace/extern/), tools/ and scripts/ that had no per-file license identifier. Each gains the minimal two-line header in the area's existing form: 'SPDX-License-Identifier: BSD-3-Clause' plus 'Copyright (c) 2026 Open-IOV contributors'; shebang and coding lines stay first. No other content touched. kernel/** is deliberately out of scope (recorded as a follow-up in CODESTD-REPORT-2026-10-08.md): its SPDX coverage and MODULE_LICENSE normalization need their own GPL-2.0 pass.

*	tools: durable guest counter enumeration/injection and VA reader	Arthur Hanson Rasmusson	13 days
	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.
