Martti Malmi b05c80e5f5 testing: add boringtun throughput benchmark and iperf ref-compare harness
New testing/boringtun/ harness runs two Cloudflare BoringTun userspace
WireGuard containers with iperf3 between them, giving a single-hop
userspace tunnel baseline for comparison against FIPS throughput
numbers. Local WG key generation runs through the harness image so the
host needs no wireguard-tools.

New testing/static/scripts/iperf-compare-refs.sh builds two git refs
into separate fips-test:* images via git worktree and runs the same
static iperf topology against both, with RUNS-based repetition and
aggregate avg/min/max reporting.

testing/static/scripts/iperf-test.sh gains DURATION, PARALLEL,
SETTLE_SECONDS, IPERF_TIMEOUT env knobs and a per-path iperf timeout.
testing/static/docker-compose.yml selects the image under test via
FIPS_TEST_IMAGE; testing/scripts/build.sh respects CARGO_TARGET_DIR.

Author benchmark on aarch64 Docker Desktop:
  boringtun bob -> alice : 1000.13 Mbits/sec
