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.
Replace impacket's SimpleSMBServer with a hand-rolled asyncio SMB2
framer that walks Negotiate -> SessionSetup(Type1) -> SessionSetup(Type3)
just deep enough to extract the inner NTLMSSP Type 3 via the shared
parse_type3() parser. Always returns STATUS_LOGON_FAILURE; the
attacker's hash lands in the Credential table, the attacker doesn't
land on the host.
- decnet/engine/deployer.py: _sync_ntlmssp_sources() mirrors the
auth-helper / sessrec sync pattern, copies _shared/ntlmssp.py into
smb/ and rdp/ build contexts before docker compose up.
- Dockerfile: drop impacket dep, copy ntlmssp.py.
- 7 unit tests drive the asyncio handler in-process via
StreamReader.feed_data; assert dialect, MORE_PROCESSING_REQUIRED on
first SessionSetup, NTLMSSP Type 2 carriage in SPNEGO, credential
capture with universal SD shape, STATUS_LOGON_FAILURE on Type 3,
oversized-NBSS / SMB1 / short-PDU drops.
