SearXNG: trusted group needs Caddy XFF; trust the podman bridge

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.

+Access SearXNG through Caddy (`search.dankclaw.local`). A direct request on the published port has no `X-Forwarded-For` header. The bot-detection cannot resolve the client and returns 429. The podman bridge subnet is in `trusted_proxies` so Caddy's request is trusted. The bridge CIDR is assigned dynamically by rootless podman.

 ## Gotchas
 
 - The JSON API is rate-limited hard by the limiter (4 per 3600s per IP for untrusted). Add the agent's IP to `pass_ip` in `limiter.toml` if it polls.
+- Reach SearXNG through Caddy, not the raw published port. A direct port hit has no `X-Forwarded-For` header and the bot-detection returns 429.
 - `base_url` must match the public address or proxy rewrites break.
 - Keep the valkey cache container on the same podman network as searxng.
