Subject: [PATCH] feat: PowerShell uninstall script for Windows

Removes only ctask-owned files from %LOCALAPPDATA%\ctask\bin. Removes PATH
entry only if .ctask-path-added marker exists (ownership tracking). Cleans
empty install directory. Never touches workspace data.

+.SYNOPSIS
+    Uninstall ctask from %LOCALAPPDATA%\ctask\bin on Windows.
+.DESCRIPTION
+    Removes ctask binary and status-line helpers from the install directory.
+    Removes the install directory from user PATH only if the install script
+    originally added it (tracked via .ctask-path-added marker).
+    Does NOT remove workspace data, CTASK_ROOT, or any task folders.
