Module analysis 

The analysis module surfaces the results of FFmpeg detector/measurement filters (blackdetect, silencedetect, scdet, cropdetect, ebur128) as typed Rust events and a folded report, instead of only FFmpeg logs. Detection / measurement result surfacing.

FFmpeg’s detector filters (blackdetect, silencedetect, scdet, cropdetect, ebur128) produce their value as data — attached to frames as lavfi.* metadata. This module reads that metadata off the frame pipeline and surfaces it as typed [MetadataEvent]s (via a [MetadataEventFilter] streamed to a user [EventSink]) or as a folded [AnalysisReport] from the one-shot [Analysis] runner.

Only per-frame metadata is covered; end-of-run log summaries such as loudnorm print_format=json are out of scope (use ebur128 metadata for loudness instead).
