Keep Codex user questions answerable

[maheen-ejaz]

Human comments

What was wrong

Codex app-server item/tool/requestUserInput was not recognized by the Codex provider bridge, so Codex was forced onto the fallback plugin path. The durable pending-interaction lifecycle already supports thread-scoped questions, but native Codex requests could not reach it and stale submissions had no clear recovery action.

What changed

• Added Codex app-server user-input request decoding and response encoding, including option/free-text answers and secret-input rejection.
• Marked the Codex provider as native-question capable so the fallback tool is withheld for Codex.
• Added a five-minute fake-timer persistence regression and provider re-registration coverage.
• Added stale-question UI recovery that refreshes pending-interaction state.
• Added adapter, provider-gating, server lifecycle, and UI regression tests.

No daemon wire protocol fields changed.

How you verified

• Focused provider, plugin, server, agent-runtime, and app tests passed.
• Affected typechecks passed for @bb/server, @bb/app, bb-plugin-ask-user-question, and bb-plugin-provider-codex.
• Formatting and git diff --check passed.
• The repository has no check:pr script.
• The source app launched successfully in an isolated dev instance; live pending-card driving was not completed because the synthetic CLI fixture did not persist into that isolated store.
