Window controls not adapted for macOS

[ewfian]

Window control buttons (minimize, maximize, close) are currently positioned on the right side of the title bar, following Windows conventions. On macOS, these buttons should be on the left side to match platform standards.

Current Behavior

• Controls are on the right side across all platforms
• Same layout for Windows, macOS, and Linux

Expected Behavior

• macOS: Controls on the left (Close - Minimize - Maximize)
• Windows/Linux: Controls on the right (Minimize - Maximize - Close)

Suggested Implementation

Detect platform using process.platform === 'darwin' and conditionally position/order the control buttons accordingly.
