Wire up EnableSubtitleExtraction config to MediaEncoder.CanExtractSubtitles so the setting is actually respected. Gate subtitle extraction check behind PlayMethod.Transcode since DirectPlay has no competing ffmpeg process. Add parameterized tests for StreamBuilder.GetSubtitleProfile covering text and graphical codecs, profile format matching, and extraction setting behavior. Remove misplaced SubtitleEncoder extraction test.

This seems to make sense. I applied it locally and did some testing, and it doesn't appear to cause any regressions in PlayMethod.Transcode.

MediaEncoder.CanExtractSubtitles()check theEnableSubtitleExtractionencoding option instead of always returningtrue. This causesStreamBuilderto select burn-in (Encode) instead of external delivery for embedded subtitles during transcoding, preventing a separate ffmpeg extraction process from competing with the transcode for network bandwidth.The check is scoped to transcoding only — during DirectPlay, subtitle extraction is still allowed since there is no competing transcode process.
