The event loop ignored Event::Update when showing the file dialog, causing next_repo_refresh to never be updated after expiration. This resulted in poll() returning immediately with zero timeout, creating a busy loop. Changed if-let to match statements that handle both Event::Input and Event::Update, updating the refresh timer in both branches.
Multiple places used len() - 1 which causes unsigned integer underflow when length is 0, wrapping to usize::MAX. This caused invalid comparisons in bounds checks and subsequent out-of-bounds index access. Changes: - Added guard for empty indices in graph_view render function - Changed len() - 1 to len().saturating_sub(1) throughout - Used safe .get(idx).copied() instead of direct indexing - Pre-computed max index values to avoid repeated calculations
