Added
- Analytics: Project filter dropdown in Analytics window header to drill down into per-project metrics (sessions, messages, duration, time series, agent breakdown, heatmap). Works alongside existing date range and agent filters.
Fixed
- Analytics: Session counts now match Sessions List by properly applying filter defaults (HideZeroMessageSessions and HideLowMessageSessions both default to true). Previously Analytics counted all sessions including noise (0-2 messages), inflating counts by up to 79%.
- Analytics: Simplified UserDefaults reading in AnalyticsRepository to use consistent pattern with AnalyticsService.
- Analytics: Project filter list now excludes projects with only empty/low-message sessions, matching Sessions List behavior.
