Visible terminal flashes on Windows from focus-check PowerShell spawns

Problem

On Windows, every focus check spawns a visible powershell.exe / pwsh.exe window that flashes on screen before closing.

Cause

src/focus.ts:101-106, getWindowsActiveWindowId() doesn't pass -WindowStyle Hidden:

let windowId = execFileWithTimeout("powershell", ["-NoProfile", "-NonInteractive", "-Command", script], 1000)
if (!windowId)
  windowId = execFileWithTimeout("pwsh", ["-NoProfile", "-NonInteractive", "-Command", script], 1000)

This runs on every notifier event. The PowerShell Operational log shows it firing every 10-30 seconds during active sessions.

Fix

Add "-WindowStyle", "Hidden" to both calls:

let windowId = execFileWithTimeout("powershell", ["-NoProfile", "-NonInteractive", "-WindowStyle", "Hidden", "-Command", script], 1000)
if (!windowId)
  windowId = execFileWithTimeout("pwsh", ["-NoProfile", "-NonInteractive", "-WindowStyle", "Hidden", "-Command", script], 1000)

Tested locally. Same return value, no visible window.

I have made this change for now. Will dig deeper into this once opencode v2.0 releases with the new plugins core structure and all the changes. Thanks for reporting this
