Implement multi-client requestInteractions and askYesNo for CLI client

[GeorgeNgMsft]

Core feature — enhancedConsole.ts: Implemented requestInteraction in the CLI's ClientIO, replacing the previous no-op stub. The CLI can now handle server-pushed interaction requests (e.g. askYesNo prompts) in real time:

Displays a styled yes/no prompt to the user using readline
Temporarily pauses any active spinner while awaiting input
Responds back to the server via dispatcher.respondInteraction()
Handles concurrent interactions from multiple clients — uses an AbortController per interactionId so that if another client responds first, the local prompt is dismissed cleanly
Tests — new multiClientInteraction.spec.ts (370 lines) with full Jest setup (jest.config.js, test/tsconfig.json) covering the multi-client interaction flow.

Docs — multi-client-interactions.md: design doc explaining the deferred interaction pattern for multiple concurrent clients.

Key design detail
Each pending interaction is tracked in activeInteractions: Map<string, AbortController>. When the server signals that another client already responded (resolved-by-other), the AbortController fires and the local question() call is cancelled without requiring user input.

Pull request overview

This PR implements real deferred-interaction handling in the TypeAgent CLI ClientIO so the CLI can respond to server-pushed prompts (e.g., askYesNo, popupQuestion) in multi-client AgentServer sessions, and adds Jest-based coverage plus a protocol/design doc.

Changes:

• Implemented requestInteraction / interactionResolved / interactionCancelled in createEnhancedClientIO, including prompt rendering, spinner pausing, and abort-based dismissal.
• Added CLI Jest + ts-jest ESM test setup and a new multi-client interaction test suite.
• Added an AgentServer design doc describing the multi-client deferred interaction protocol.

Since you're doing this could you look into also wiring this through for the reasoning loop? It'd be great if we could surface those questions to the user.
