fix(windows): improve worker stop/restart reliability (#395)

* fix(windows): enable worker logging on Windows

Previously, Windows worker startup via PowerShell Start-Process did not
redirect stdout/stderr to log files, making debugging startup failures
impossible. This adds -RedirectStandardOutput and -RedirectStandardError
to capture worker logs to ~/.claude-mem/logs/worker-YYYY-MM-DD.log.

* fix(windows): improve worker stop/restart reliability

- Use HTTP shutdown endpoint as primary stop method (worker kills itself)
- Only remove PID file after confirming worker is actually dead
- Remove auto-respawn from wrapper to prevent PID file mismatches
- Wrapper now exits when inner worker crashes (hooks will restart)

This hopefully fixes issues where npm run worker:stop would fail silently when
the worker was started from hooks, leaving zombie processes.
