feat(diagnostics): Add granular logging to ActivityPoller initialization

- Add logging before/after AWS config loading
- Add logging before/after SFN client creation
- Add logging before/after ScriptExecutor creation
- Add logging before struct construction

This helps identify exactly where Windows initialization hangs.
