Tier 2 dev workflow: Windows test runner + result sync

- run_tests.bat: double-click test runner with JSON result capture
- run_script.bat: run any script with output capture
- test_results/ folder for Syncthing-based result sharing
- Auto-mark NX-dependent tests for --quick mode
- pytest-json-report for structured results
