Subject: [PATCH] Refactor WebRenderer to use server-side streaming with
 OGG-FLAC sink

This commit refactors the WebRenderer to use a server-side streaming architecture with OGG-FLAC sink instead of the previous WebSocket-based approach. The changes include:

- Replaced WebSocket communication with HTTP streaming using DirectOggFlacSink
- Implemented a new pipeline architecture with dedicated handlers for UPnP commands
- Added new modules for registration, registry, and streaming
- Updated the renderer to work with a pipeline control system
- Removed old WebSocket session management
- Added support for HTTP streaming with gapless playback
- Updated dependencies and features for the new architecture

The WebRenderer now acts as a MediaRenderer UPnP device that serves audio streams via HTTP endpoints, with commands relayed to the audio pipeline through a new control system.

- * 1. SetAVTransportURI(N)     → slotA.src = N, slotA.load()
- * 2. Play                     → slotA.play()

+//! DirectFlacSink — nœud puits FLAC pour un seul client HTTP.
+//!
+//! Encode l'audio en FLAC (format fixe : 96 kHz / stéréo / 24 bits).
+//!
+//! # Cycle de vie
+//!
+//! - **Play** : le navigateur appelle `GET /stream`. `connect()` crée un nouveau
+//!   canal PCM + pipe duplex + encodeur FLAC, installe le sender dans le sink,
+//!   et notifie le sink via `client_notify`. Le flux reste ouvert : les morceaux
+//!   s'enchaînent en gapless.
+//! - **Stop** : le navigateur ferme la connexion. Le pipe se rompt, l'encodeur
+//!   s'arrête. Le sink voit `pcm_tx.send()` échouer, passe le sender à `None`,
+//!   et **bloque** sur `client_notify` jusqu'au prochain Play.
+//!   Cela bloque la source et préserve la backpressure.
+//! - **Play suivant** : `connect()` → nouveau pipe → `client_notify.notify_one()`
+//!   → le sink se débloque et reprend la consommation des segments.
+//!
+//! # Architecture
+//!
+//! ```text
+//! AudioSegment I24 @ 96 kHz
+//!     ↓ NodeLogic::process()  [bloque si pas de client]

+//! DirectOggFlacSink — nœud puits OGG-FLAC pour un seul client HTTP.
+//!
+//! Combine la logique de backpressure/reconnexion de `DirectFlacSink`
+//! avec l'encodage OGG-FLAC de `StreamingOggFlacSink`.
+//!
+//! # Cycle de vie
+//!
+//! - **Play** : le navigateur appelle `GET /stream`. `connect()` crée un nouveau
+//!   canal PCM + pipe duplex + encodeur FLAC + wrapper OGG, installe le sender
+//!   dans le sink, et notifie le sink via `client_notify`. Le flux reste ouvert :
+//!   les morceaux s'enchaînent en gapless.
+//! - **Stop** : le navigateur ferme la connexion. Le pipe se rompt, l'encodeur
+//!   s'arrête. Le sink voit `pcm_tx.send()` échouer, passe le sender à `None`,
+//!   et **bloque** sur `client_notify` jusqu'au prochain Play.
+//! - **Play suivant** : `connect()` → nouveau pipe → `client_notify.notify_one()`
+//!   → le sink se débloque et reprend la consommation des segments.
+//!
+//! # Architecture
+//!
+//! ```text
+//! AudioSegment I24 @ 96 kHz
+//!     ↓ NodeLogic::process()  [bloque si pas de client]
+//! chunk_to_pcm_bytes() → PCM 24-bit LE
+//!     ↓ Arc<Mutex<Option<mpsc::Sender<PcmChunk>>>>
+//! ByteStreamReader (AsyncRead)
+//!     ↓ encode_flac_stream()
+//!     ↓ broadcast_ogg_flac_stream() → wrapping OGG pages
+//!     ↓ tokio::io::duplex pipe (256 KB)
+//!     ↓ DirectOggFlacStream (AsyncRead) → Body HTTP
