fix(vscode): support reviewing question answers

[ousamabenyounes]

Fixes #2350.

Summary

• keep AskUserQuestion choices in an explicit review flow instead of advancing or submitting on selection
• support multi-select options, custom-only answers, and combined preset/custom answers
• let users navigate back without losing selections and require an explicit final submission
• allow users to remove a previously saved custom multi-select answer while preserving preset selections
• prevent duplicate question RPCs while submission is in flight
• add reducer-level and React/jsdom interaction coverage

Test verification (RED → GREEN)

• RED: the original flow tests failed before the question-flow implementation existed
• RED follow-up: clearing a reviewed custom answer left an empty custom key and the UI disabled saving the removal (2 focused failures)
• GREEN: targeted reducer and React interaction suite passes all 8 tests
• VS Code extension suite: 16 files / 316 tests passed
• full local suite: lint, typecheck, production build, 1,037 files and 16,905 tests passed versus the upstream baseline of 1,035 files and 16,897 tests
• independent code review: PASS

[ousamabenyounes]

Addressed the review-flow edge case in ef1693adf: clearing a saved custom multi-select response now removes it while retaining selected preset options; new blank custom responses remain blocked.

Validation: reproduced 2 focused RED failures, then 8/8 focused tests GREEN. run-ci.sh improved from the upstream baseline of 16,897 passing tests to 16,905 with lint, typecheck, and build GREEN. GitHub currently reports no visible checks for this exact SHA.
