fix(vscode,cli): make plan_exit "Continue here" work again

Restore custom: false on the plan follow-up question — the "Type your own answer" row was redundant because the main prompt already routes typed text as a question reply. Auto-submit single-question single-select option picks in the VS Code QuestionDock so the button behaves like the TUI instead of silently waiting for a second Submit click.
