Signal Lab 0.3.1 (pre-release)

First pre-release. Functionally the same as 0.3.0 — the signal library and the
MQTT client — but built from the commit that fixes two job-telemetry races and
makes Stop actually stop the work. The 0.3.0 installers predated those fixes, so
a scan could report an empty table and Stop could leave traffic running.

Verified on this release build, each against an independent reference:

• Scanner — returns exactly the ports a separate connect-sweep finds (28/28 over 1–10000).
• Stop — measured with UDP sinks: storm 1740 packets while running → 0 after stop; impairment relay 5/5 forwarded → 0/5 after; scan progress freezes and the registry empties.
• HTTP — methods, headers, body, status codes, timeout, 500 KB body truncation; burst sends exactly N (confirmed by the target's own hit counter), runs workers concurrently, and ends on its duration.
• Broadcast — list fan-out, byte-exact text and hex payloads, CIDR sweep (network and broadcast addresses excluded), the 1024-host cap, multicast delivery to a real group member, beacon rate, and discovery auto-reply.
• Impairment — loss, duplication and corruption ratios match the profile; corruption flips exactly one bit; latency lands within tolerance.
• Inspector — protocol/direction/text filters, .jsonl and .txt export, and honest overflow accounting under a 20 000 pkt/s flood (31 602 captured, 27 352 reported as not shown).
• MQTT — against a real eclipse-mosquitto, with the reference JS client on the far end: retained-value scan, QoS 1/2 exactly once, retained clearing, last-will on drop.

cargo test 37/37, zero compiler warnings, layout clean at 1280 px and 980 px in both locales.

Limitations

• Windows x64 only; macOS and Linux are not built or tested.
• Installers are unsigned — SmartScreen will warn about an unknown publisher.
• Tested on one development machine; not yet verified on a clean Windows install.

Responsible use: Storm, Scanner and Broadcast generate real traffic and probe
real hosts. Point them only at equipment you own or are authorised to test.
