Fixes incorrect sample_rate() and channels() metadata returned by SourcesQueueOutput when transitioning between sources with different formats or from an empty queue. This caused audio distortion at boundaries where metadata changes occurred. Changes: - Clarified Source::current_span_len() contract: returns total span size, Some(0) when exhausted - Fixed SamplesBuffer to return Some(total_size) or Some(0) when exhausted (was None) - Fixed SamplesBuffer::size_hint() to return remaining samples - Updated SourcesQueueOutput to peek next source metadata when current is exhausted - Added Source::is_exhausted() helper method for cleaner exhaustion checks throughout codebase - Implemented ExactSizeIterator for SamplesBuffer - Improved SkipDuration precision to avoid rounding errors This supersedes PR #812 with a cleaner implementation following the proper current_span_len() contract. Enabled previously ignored queue::tests::basic test to prevent regressions. Fixes #811 Co-authored-by: 0----0 <9070490+0----0@users.noreply.github.com>
