TASK-48.3	Implement stream subtitle selection and primary-language precedence	To Do		2026-02-14 06:03	2026-02-14 08:19	stream subtitles		TASK-48	high

Description

Handle subtitle track selection for stream playback so Japanese (or configured primary language) subtitle behavior is correctly applied when stream metadata includes or omits JP tracks.

Acceptance Criteria

• #1 Use stream metadata to choose and mark the configured primary language subtitle as active when available.
• #2 If no matching primary language track exists in stream metadata, keep previous fallback behavior only for non-streaming mode.
• #3 When no Japanese track exists and config primary is different, explicitly set configured primary as primary track for streaming flow.

Implementation Notes

Superseded by TASK-51. Stream subtitle language precedence in streaming mode deferred with full design revisit.
