Update SearXNG, Gluetun, and Valkey to describe the quadlet units instead of
compose: searxng sets Network=gluetun.container, the units install to
~/.config/containers/systemd/, and scripts/deploy-searxng-quadlet.sh deploys
them. Add a Boot Persistence section to the Stack doc. Correct the Gluetun
tunnel check (the :8000 server 404s; verify tun0 instead) and note the pinned
10.89.2.0/24 subnet.
A direct hit on the published port has no X-Forwarded-For header, so the
bot-detection cannot resolve a client and returns 429. SearXNG must be
reached through Caddy (search.dankclaw.local), which sets X-Forwarded-For.
Add the podman bridge subnets to trusted_proxies so Caddy's source is
trusted for XFF extraction; note the CIDR is dynamic and should be pinned.
Verified agentic JSON search returns 26-31 relevant results via this path.
The trusted group lives in limiter.toml, not settings.yml. Add
shared/searxng/limiter.toml trusting 192.168.0.0/24 in pass_ip and
trusted_proxies, copy it into /opt/searxng/config on deploy, and correct
the SearXNG doc. New test seam: tests/searxng_limiter.bats.
