Adds a digest-pinned headless-shell Chrome DevTools Protocol daemon as a
boot-persistent quadlet unit (chrome-devtools-protocol.container). The
entrypoint override drops the image's socat front so the CDP endpoint binds
loopback-only on 127.0.0.1:9222 in the host network namespace; only the two
host-network consumers (Signal gateway, webui server) can drive it.
hermes-webui flips Network=dankclaw_default -> Network=host so its agent
process shares the daemon's namespace (0.0.0.0:8787 bind is LAN-facing as
before; no exposure change). deploy_hermes installs the new unit and starts
it if inactive without restarting in-flight browser sessions.
Verified live 2026-08-31: guarded path serves the Anubis JS challenge at
HTTP 200 to non-browser API clients (status-only consumers silently get
HTML); direct published port 8081 from pass_ip sources returns real JSON.
Decision: no second agent-only instance — same engines and same
rate-sensitive VPN exit IP would see double request volume for zero gain.
Server-side implementation landed on Dankclaw: dedicated 'tunnel' account
(nologin shell, password-locked, key-only auth), sshd drop-in
99-tunnel.conf scoping AllowTcpForwarding to that user with PermitTTY off,
and permitopen="localhost:8787" key-option guidance so a leaked tunnel key
can only forward to the webui port. WebUI stays loopback-only published.
All in-repo path references (AGENTS.md, README, old scripts, report artifacts,
test code paths) rewritten in the same commit; focused-test map extended for
.gitignore, old/scripts/*, dankclaw/comfyui/*, and report/* per this repo's
own convention ('add one before committing'). Obsidian wikilinks are
title-based and unaffected.
