First per-module ratchet under ADR 0004. Extend the adapter flow suite
to cover the remaining behavioural gaps:
- inbound response DLP: injection block (403), warn (logged, forwarded),
and LOG_FULL response logging
- WebSocket inbound (server->client) scanning: injection kills the
connection; warn does not; no-websocket is a no-op
- redaction scrubs the token in a header and the request path, not just
the body
- supervise queue-write OSError fails closed (403)
- _token_allow_timeout_from_env: unset/valid/non-numeric/non-positive
- SIGHUP handler reloads routes; a reload failure keeps the last good
config
- LOG_FULL logs the forwarded request
egress_addon.py: 76% -> 94%. The remaining misses are the low-value
edges (no-SIGHUP platform, hostname-redaction-fails-closed) called out
in the egress adapter PR.
