report_progress now fills peer_stats via engine_peer_list, so the peer
list (ip, progress, dl rate, state) shows again. Mark #12 done.

Address the review of the webui plugin:
- Live download rates. A background sampler polls the daemon once per
second, derives per-torrent dlspeed from successive byte counts (EWMA
smoothed), and computes a real ETA. dl_info_speed now aggregates the
fleet instead of reporting a hardcoded 0.
- Single shared snapshot. The sampler publishes one cached snapshot that
/api/snapshot, /api/torrents and every SSE stream serve, so N browser
tabs no longer each poll the engine and race the speed table. SSE
waiters block on a condition and wake promptly on shutdown.
- Honest /api/action. The engine has no pause/resume/recheck/queue verbs,
so the endpoint returns 501 with an explanatory message instead of
claiming success.
- Reject oversized uploads with 413 instead of silently truncating a
torrent into garbage.
- Auth hardening: constant-time credential comparison, CSPRNG-only token
generation via getrandom (fail closed, no weak fallback), oldest-session
eviction instead of clobbering slot 0, and a warning when bound to a
non-loopback address.
- Cap concurrent connections (503 beyond the limit) so a client can't
spawn unbounded threads.
- nautd: tear down plugins (joining the webui's threads) before freeing
torrent tasks, closing a shutdown-time use-after-free window where an
in-flight request could touch freed state.

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.
