feat(cli): pass AskUserQuestion answers via permission RPC

[dragonkid]

Summary

• When a permission response includes an answers field (Record<string, string>), merge it into the tool's updatedInput so Claude Code receives structured user selections in the AskUserQuestion tool result
• Enables remote clients (mobile app, Discord bot) to send selected answers through the existing permission RPC without a separate sendMessage call
• No breaking changes — the answers field is optional and backward-compatible

Changes

packages/happy-cli/src/claude/utils/permissionHandler.ts

• Added answers?: Record<string, string> to PermissionResponse interface
• Updated handlePermissionResponse to merge response.answers into updatedInput

Context

Currently, remote clients like the Discord bot must use a two-step flow to answer AskUserQuestion:

1. approvePermission (RPC) — approves the tool call
2. sendMessage (HTTP) — sends the answer text separately

This causes Claude to treat the answer as a new user message ("Other" free-text input) rather than a structured selection. With this change, answers are passed directly through updatedInput.answers, which the Claude Code SDK natively supports.

Test plan

• Smoke test: trigger AskUserQuestion from Claude Code, answer via remote client with answers field in permission response
• Verify Claude sees structured selection (e.g., "The user selected 'PostgreSQL'") instead of "Other" free-text
• Verify existing permission flow (approve/deny without answers) still works
