The mitmproxy adapter `egress_addon.py` was omitted from coverage
because it can't import on the host (mitmproxy is sidecar-only) and
only its log-redaction helpers were exercised. Add a request/response
flow suite that stubs mitmproxy and drives the adapter glue:
introspection, allowlist enforcement, auth strip+inject, git
push/fetch blocking, the outbound-DLP block/redact/supervise policy
branches (including the operator approval round-trip), inbound
response scanning, and WebSocket frame scanning.
Removes the `bot_bottle/egress_addon.py` omit from `.coveragerc`;
the adapter now reports ~76% covered.
Closes#286
