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.

Touches 1565 source files (.py, .ts, .tsx, .js, .jsx, .css, .sh).
No behavior change; comments only.
Mirrors the inode-check fix from 935a9a5 (collector worker) for the
stdlib-handler-based log paths. Both decnet.system.log (config.py) and
decnet.log (logging/file_handler.py) now use a subclass that stats the
target path before each emit and reopens on inode/device mismatch —
matching the behavior of stdlib WatchedFileHandler while preserving
size-based rotation.
Previously: rm decnet.system.log → handler kept writing to the orphaned
inode until maxBytes triggered; all lines between were lost.
'sudo decnet deploy' needs root for MACVLAN, but the log files it creates
(decnet.log and decnet.system.log) end up owned by root. A subsequent
non-root 'decnet api' then crashes on PermissionError appending to them.
New decnet.privdrop helper reads SUDO_UID/SUDO_GID and chowns files/dirs
back to the invoking user. Best-effort: no-op when not root, not under
sudo, path missing, or chown fails. Applied at both log-file creation
sites (config.py system log, logging/file_handler.py syslog file).
Extends tracing to every remaining module: all 23 API route handlers,
correlation engine, sniffer (fingerprint/p0f/syslog), prober (jarm/hassh/tcpfp),
profiler behavioral analysis, logging subsystem, engine, and mutator.
Bridges the ingester→SSE trace gap by persisting trace_id/span_id columns on
the logs table and creating OTEL span links in the SSE endpoint. Adds log-trace
correlation via _TraceContextFilter injecting otel_trace_id into Python LogRecords.
Includes development/docs/TRACING.md with full span reference (76 spans),
pipeline propagation architecture, quick start guide, and troubleshooting.
dict[str, Any] and X | Y union syntax require Python 3.10+. Containers
running centos7/ubuntu20/rocky9 base images ship Python 3.6-3.9 and
crashed on import. Adding the __future__ import makes all annotations
lazy strings, compatible back to Python 3.7.
Affected: templates/decnet_logging.py (+ all 22 template copies),
decnet/logging/syslog_formatter.py, decnet/logging/file_handler.py
