- Added unit tests for renderSegmentTrack verifying per-segment coloring, active chip fill formatting, and active-index movement.
- Added tests for theme.getContrastFgAnsi to ensure selected foreground contrast remains clearly readable against RGB fills.
- Removed the OAuth selector keybinding test and its local auth-storage scaffolding, and documented the new model-tier/role-cycle chip-track behavior in the changelog.
Replaced raw Up/Down arrow matching in selector-style components with the shared tui.select navigation keybindings.
Added regression coverage for Ctrl+P/Ctrl+N selector remaps across the reported components.
Fixes#1535
