v0.2.10

Highlights

Polish release: per-line transcript audio replay (▶ on hover, exact span from the
wall-clock-aligned retained WAV), delete buttons for bad summaries/compressions,
per-session expected-speaker count next to Identify speakers (replaces the global
setting in the UI), and sidebar improvements — date + relative time in session
meta, drag-resizable divider with persisted width.
