v3.1.3

- Bare Git repositories show an empty state instead of surfacing an error.
- Ticket lists no longer flash a bogus “network request failed” message while scrolling.
- Paste detail opens as a full-screen file-style viewer.
- Optional AMOLED-style true-black list rows (via themedRow).
- Trackers load every page when opened so the Open tab count stays accurate.
- Centralized Hutch/SourceHut URLs, leaner Project and contribution-stats models,
  explicit SwiftUI bindings where @Bindable was awkward, and small reliability
  cleanups across services and widgets.
