RegisterAutostartStep rewrote the Startup .lnk on every install/update/repair
even when it already pointed at the right worker exe. AutostartShortcut.Install
now reads the existing shortcut's target via ShortcutFactory.TryGetTarget and
skips the rewrite when it matches, reporting the skip in progress output.
Legacy service/scheduled-task cleanup stays unconditional (migration safety net).
Replaces schtasks /Create with AutostartShortcut.Install; migrates away
legacy scheduled task and Windows service on upgrade. Removes ScheduledTaskXml.

A LocalSystem Windows service can't see the logged-in user's Claude CLI
authentication, so the worker now runs as the current user via a hidden
per-user logon Scheduled Task with restart-on-failure.
- Worker is WinExe (no console window) with a Serilog rolling file sink and
a single-instance mutex so the logon task, app ensure-running, and Restart
button can't fight over the SignalR port.
- Installer replaces the service steps (register/start/stop) with autostart
task steps, migrates the legacy ClaudeDoWorker service away on update, and
removes the task on uninstall. ServicePage drops the service-account UI.
- UI gains a WorkerLocator; the app ensures the worker is running at startup
and the Restart button kills+relaunches this install's worker process.
