DemonGatanjieuandClaude Opus 5.5 6f4347d88d Settings -> Network: a proxy for the plugin, and why Civitai cannot be reached
A Bilibili user's scan said Civitai could not be reached while their
browser reached it through a VPN app: the plugin's urllib requests only
use HTTPS_PROXY or the Windows proxy, not a PAC script or a browser-only
proxy.

net_proxy.py: the proxy address saved in api/config.json (NETWORK_PROXY)
that every request of the plugin goes through (Civitai, Hugging Face,
GitHub, translators), handed to the scan process as HTTP(S)_PROXY; empty
keeps the old behaviour. It also names why a request failed (timeout,
refused, dns, ssl, reset, proxy, http:<code>).

Settings -> Network has the address (SOCKS and malformed ones refused
with what to write) and Test connection, which calls 1.60's
/anomalous/civitai_check (brought here unchanged, now through the proxy
and with the failure's name). A scan that loses Civitai records why
(civitai_error) and the scan page and activity log say it with what to
try.

"""What only this computer may do. ComfyUI started with --listen lets other devices on the
network open the page: they may look (lists, searches, pictures, covers), but every change
under /anomalous/ (writing, moving and deleting files, downloads, scans, translations, backups,
version switches, saved settings) answers only requests from the computer ComfyUI runs on
(AGENTS.md 安全底线, rule 4). One middleware decides it for all routes: a request other than
GET is local-only unless it is a read sent as POST (OPEN_POSTS); a GET is open unless it is not
a plain read (LOCAL_GETS). A request is local when it comes from a loopback address, through no
proxy, naming a loopback host; checking the Host also keeps out a page that reached this server
under another name (DNS rebinding)."""
