* fix(deezer): Use GraphQL API for translated biographies

The previous implementation scraped the __DZR_APP_STATE__ from HTML,
which only contained English content. The actual biography displayed
on Deezer's website comes from their GraphQL API at pipe.deezer.com,
which properly respects the Accept-Language header and returns
translated content.

This change:
- Switches from HTML scraping to the GraphQL API
- Uses Accept-Language header instead of URL path for language
- Updates tests to match the new implementation
- Removes unused HTML fixture file

This folder abstracts metadata lookup into "agents". Each agent can be implemented to get as much info as the external source provides, by using a granular set of interfaces (see interfaces).

A new agent must comply with these simple implementation rules:

  1. Implement the AgentName() method. It just returns the name of the agent for logging purposes.
  2. Implement one or more of the *Retriever() interfaces. That's where the agent's logic resides.
  3. Register itself (in its init() function).

For an agent to be used it needs to be listed in the Agents config option (default is "lastfm,spotify"). The order dictates the priority of the agents

For a simple Agent example, look at the local_agent agent source code.
