From 8dde48c05a3dcffb17b7ff2462c86586e0e276f2 Mon Sep 17 00:00:00 2001 From: ookami125 Date: Wed, 17 Jun 2026 00:21:48 -0400 Subject: [PATCH] webui: replace nautctl web server with a loadable plugin Drop the web UI that was compiled into nautctl and serve the torrent-ui front end (../torrent-ui/public) from a native plugin (plugins/webui) loaded via `nautd --plugin`. The plugin talks to the engine only through the host call_rpc ABI and adapts the daemon's RPC surface to the qBittorrent-style contract the UI expects (snapshot/SSE, torrent detail tabs, add/delete, cookie auth). Also folds in the daemon refactor that owns per-torrent worker threads and the swarm engine (naut_swarm) used by the plugin's data source.
