Replaces the generic `headers` configuration field with a specific `origin` field for Apple Music. Updates the config schema, environment variable handling, documentation, and source implementation to simplify origin header management.
Added logic to detect and recover 'top-rebound' history patterns where Apple Music deduplicates re-listened tracks by bumping them to the top. This ensures intermediate tracks are captured and re-listened top tracks are processed correctly. Includes a new configuration option `recoverUnchangedTopHistory` to toggle this behavior.
Introduced a `headers` configuration option to allow setting custom request headers, such as 'Origin', for Apple Music API requests. Updated configuration schema and source implementation to apply these headers.
