Copilot agents use vscode_askquestions as the equivalent of AskUserQuestion.
Without explicit guidance they sometimes omit questioning steps that depend
on AskUserQuestion, causing extra billing and incomplete workflows.
- Add <runtime_note> to plan-phase, discuss-phase, execute-phase, and
new-project commands mapping vscode_askquestions to AskUserQuestion
- Add AskUserQuestion to plan-phase allowed-tools (was missing, causing
the planner orchestrator to skip user questions in some runtimes)
