Window position/size settings are not saved on multi-monitor setup (Tauri window state bug)

Description

Description

The desktop application does not remember its size and position on a multi-monitor setup. On every launch, it ignores the saved coordinates in .window-state.json and opens on the wrong display or expands beyond the monitor screen boundaries.

This appears to be a known initialization race condition with tauri-plugin-window-state where the window initializes before reading the config.

Steps to Reproduce

1. Use a dual-monitor setup (Laptop + external display, with the external display set as primary).
2. Open OpenCode, move it to the left half of the external monitor, and close the app.
3. Reopen the app.

Expected Behavior

The window should accurately restore its position on the left half of the external monitor according to the .window-state.json file.

Actual Behavior

The application ignores the config (even if set to Read-only), resets isMaximized flags arbitrarily, and opens on the laptop screen or randomly across monitors.

Environment

• OS: Windows 11
• App Version: Latest Desktop Release (Tauri-based)
• Monitor Setup: Dual-monitor (External Primary + Laptop Secondary)
