Replaces LICENSE (GPLv3 -> AGPLv3) and prepends
`SPDX-License-Identifier: AGPL-3.0-or-later` to every source file
across decnet/, decnet_web/, tests/, scripts/, and tools/.
Rationale: closes the GPLv3 ASP loophole so any party operating a
modified DECNET as a network service must offer their modified
source. Personal copyright (Samuel Paschuan) + inbound=outbound
contributions make a future unilateral relicense infeasible.

Every http_useragent bounty now carries a `category` label plus an
optional tool name and a signals list. The main analytic win is the
`nonstandard` bucket — UAs like "FUCKYOU/1.0" or custom one-off
scanner labels that don't match any known pattern, which today
silently blend into the generic fingerprint list.
Buckets (priority order):
- scanner: nmap, nuclei, sqlmap, gobuster, nikto, masscan, zgrab,
ffuf, wpscan, katana, burp, acunetix, nessus, openvas, arachni,
whatweb, wappalyzer, etc.
- cli: curl, wget, httpie, xh, fetch.
- library: python-requests, aiohttp, httpx, urllib, Go stdlib, Java,
okhttp, Apache HttpClient, axios, node-fetch, got, undici, PHP,
Guzzle, Ruby stdlib, Faraday, .NET, PostmanRuntime, Insomnia, etc.
- bot: anything containing bot / crawler / spider / slurp / monitor
(catches Googlebot, bingbot, Baiduspider — many of which ship a
Mozilla/5.0 prefix, so the bot check runs BEFORE the browser
regex).
- browser: Mozilla/5.0-prefixed UAs that aren't bots.
- nonstandard: anything else. The interesting bucket.
- empty: literal empty User-Agent header.
Side signals computed regardless of category: suspicious_short (<8
chars), suspicious_long (>512 chars), nonprintable (control chars),
injection_like (SQLi / XSS / path-traversal / Log4Shell markers).
A sqlmap UA with a literal SQL-injection payload embedded fires
category=scanner + injection_like — the combination tells the
analyst the tool is being operated manually vs. on default config.
Classification is deterministic (same UA string → same tuple) so
add_bounty's payload-hash dedup continues to collapse repeat rows.
UI renderer upgraded from FpGeneric to a dedicated FpUserAgent that
colours the category tag by risk (scanner=alert-red,
nonstandard=warn-yellow, browser=accent-green, etc.) and renders
each signal as its own chip. Makes the interesting rows pop in the
fingerprints panel.
Also fixed: the ingester was using `_headers.get("User-Agent") or
_headers.get("user-agent")`, which short-circuits away empty-string
UAs. An explicit empty UA is itself a signal (real clients always
send something) — now captured.
