[FEATURE]:add config option to disable Electron native menu accelerators (Ctrl+M/Ctrl+W) #34937

Feature hasn't been suggested before.

• I have verified this feature I'm about to request hasn't been suggested before.

Describe the enhancement you want to request

On Windows, the OpenCode Desktop app uses Electron's built-in { role: "windowMenu" } menu, which registers Ctrl+M as the "Minimize" accelerator and Ctrl+W as "Close". This cannot be disabled through opencode.json or tui.json because it's handled at the Electron/native menu level, not the TUI keybind system.

For users who want to use Ctrl+M or Ctrl+W for other purposes (or who find Ctrl+M accidentally minimizes the window), there is currently no way to disable these native accelerators.

Describe the solution you'd like

Add a config option, either in opencode.json or tui.json, to disable or customize the Electron native menu accelerators. Some possibilities:

A disable_native_accelerators flag:

{
  "desktop": {
    "disable_native_accelerators": ["Ctrl+M", "Ctrl+W"]
  }
}

Or simply an option to replace { role: "windowMenu" } with a custom Window menu that omits the minimize accelerator.
Describe alternatives you've considered

Using AutoHotkey to intercept Ctrl+M — works but requires third-party software
Manually patching the Electron app — gets wiped on every update
Neither is a proper solution for end users.

Additional context

This is related to the Electron windowMenu role which on Windows defaults to Minimize (Ctrl+M) and Close (Ctrl+W). On macOS the same role uses Cmd+M/Cmd+W which are more standard and less likely to conflict.
