Update CLI to communicate with daemon via gRPC

[andhijeannot]

Overview

Refactor the CLI to communicate with maestrod daemon via gRPC instead of direct AppleScript execution.

Scope

Update the existing CLI implementation to use client-server architecture while maintaining the same user interface.

Implementation Requirements

CLI Client Updates (presentation/cli/)

• Refactor command implementations to use gRPC client
• Add daemon connection management
• Implement automatic daemon discovery and connection
• Add connection retry and fallback logic
• Maintain existing command interface and output formats

Connection Management

• Automatic daemon startup if not running
• Connection pooling and reuse
• Health check before command execution
• Graceful degradation when daemon unavailable
• Certificate-based authentication

Success Criteria

• All existing CLI commands work via daemon
• Performance meets <100ms target for basic commands
• Connection handling is robust and automatic
• Error messages are clear and actionable
• Certificate authentication works seamlessly
• Session management integrates properly
• Backward compatibility maintained
• JSON output format preserved
