//! `tribler-feeder` — single-source BitTorrent feeder sidecar for the
//! decentralized Tribler (IPv8 overlay) network.
//!
//! One plugin (`tribler`) served through [`meta_feeder_sdk::serve_feeders`]. A
//! thin client of a headless Tribler core (reached at `TRIBLER_SIDECAR_URL`); it
//! finds records over the Tribler swarm and enriches them via the copied
//! torrent-core TMDB catalog-discovery stack. Split out of `meta-feeder-torrent`
//! so its dashboard config panel resolves to the tribler schema.
//!
//! Env (shared): `META_FEEDER_HTTP_LISTEN` (default `0.0.0.0:8080`),
//! `META_FEEDER_STATE_DIR` (default `/data/meta-feeder`), `META_CORE_URL` (D4
//! self-publish), `RUST_LOG`.
//! Env (tribler source): `TRIBLER_SIDECAR_URL`, `TRIBLER_API_KEY`,
//! `TMDB_TOKEN`/`TMDB_LANGUAGE`, plus the enrichment-plugin URLs
//! (`FILENAME_PARSER_URL`, `TMDB_PLUGIN_URL`, `META_FEEDER_CALLBACK_URL`).
