Selected rows in the model/session/skills pickers and approval/clarify prompts only changed from dim gray to cornsilk, which reads as low contrast on lighter themes and LCDs (reported during TUI v2 blitz). Switch the selected row to `inverse bold` with the brand accent color across modelPicker, sessionPicker, skillsHub, and prompts so the highlight is terminal-portable and unambiguous. Unselected rows stay dim. Also extends the sessionPicker middle meta column (which was always dim) to inherit the row's selection state.
