/**
 * Handles MPEG-TS stream requests. Validates the channel, flushes HTTP headers early for new streams, then ensures a capture is running, waits for the init segment,
 * spawns a per-client FFmpeg remuxer, and streams the output.
 *
 * For new streams, headers are flushed before stream setup begins so the client sees an immediate 200 response. This prevents timeout failures during the 4-10+
 * second startup sequence. The trade-off is that error responses cannot be sent after the flush — failures are logged server-side and the connection is closed.
 *
 * Route: GET /stream/:name
 *
 * @param req - Express request object.
 * @param res - Express response object.
