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.

No behavior change; comments only.
Plugs the cred-coverage gap for MongoDB. The template previously
parsed only the wire opcode + length and discarded the BSON body
entirely, so SCRAM-SHA-{1,256} client-proofs flowed straight through
without ever landing in the Credential table.
Adds an inline minimal BSON walker (~100 LoC) covering the 7 type
codes auth commands actually use: string, doc, array, binary, bool,
int32, int64. Hand-rolled rather than pulling pymongo as a runtime
dep — the parser is bounds-checked for untrusted-input safety
(won't loop on malformed length fields).
Wire flow MongoDB clients use for auth:
- OP_MSG body section (kind=0) → BSON doc with `saslStart` field
carrying mechanism + payload (SCRAM client-first-message:
"n,,n=<user>,r=<nonce>"). Username extracted, pinned to the
per-connection _sasl_username + _sasl_mechanism state.
- Subsequent OP_MSG with `saslContinue` → SCRAM client-final-message
("c=biws,r=<combined>,p=<base64 client-proof>"). The `p=` value is
the credential — emitted as secret_kind=scram_sha256 (or _sha1 /
_unknown depending on the prior saslStart's mechanism), principal
= the pinned username, secret_b64 = base64 of the decoded proof.
Reuse semantics: same client-proof across two auth attempts only
matches when both server salt and password were identical (proofs
include the salt). So cross-session reuse correlates only on
credential reuse against the same MongoDB account on the same decky
— honest, non-misleading signal.
680 tests pass across services, service_testing, db, web/ingester,
and core/fingerprinting (the broader scope my recent commits
touched). Phases 4, 5, 7 still pending (RDP basic-auth, SMB
NTLMSSP, RDP NLA).
