Change sendPrompt to return immediately by default instead of blocking, allowing the orchestrator to continue while agents process in the background. Add optional maxWait parameter for cases where waiting is needed.
Changes:
- sendPrompt now returns { didComplete, stopReason? } immediately if no maxWait
- Background promise handles completion and updates agent status via protocol
- Optional maxWait parameter races completion vs timeout, returns didComplete status
- Update send_agent_prompt MCP tool to expose maxWait parameter
- Agent continues processing in background even if maxWait expires
- Orchestrator can poll get_agent_status or get_agent_activity to check progress
This prevents orchestrator from blocking on long-running agent tasks while maintaining protocol-based completion tracking.

Replace all undefined values with null in agent MCP tool responses to prevent JSON serialization issues that break the MCP client.
Changes:
- Update AgentInfo interface to use `| null` instead of optional `?` syntax
- Convert undefined to null in listAgents(), getCurrentMode(), getAvailableModes()
- Update all Zod schemas from .optional() to .nullable()
- Fix tool responses in create_coding_agent and set_agent_mode
This ensures all MCP tool responses properly serialize optional fields as null instead of undefined, preventing client-side errors.

Replace client-side permission mode hack with proper ACP session modes:
- Add typed Client interface implementation to ACPClient
- Import proper types from ACP SDK (SessionNotification, RequestPermissionRequest, etc.)
- Fix critical sessionUpdate bug where params.update was undefined
- Replace PermissionMode with SessionMode from ACP spec
- Add getCurrentMode(), getAvailableModes(), setSessionMode() to AgentManager
- Update MCP tools: replace set_agent_permission_mode with set_agent_mode
- Add session_state message type to send live agents/commands to client
- Update UI to display session mode badges (ask/code/architect)
- Remove all permissionsMode references from tests
Agents now have ONE mode (session mode) that controls their behavior,
system prompts, and tool availability - not separate permission/session modes.
