fix: generate all 19 strategies/*.conf from upstream .bat files

- Add Python converter (convert_bat.py) + PowerShell wrapper generator
- All general*.sh now point to run_strategy.sh <name>
- Normalize filenames: spaces → underscores (FAKE_TLS_AUTO_ALT etc.)
- Fix sync_from_upstream.sh: underscores in names
- Update README: document modular architecture, sync, hosts

sync_from_upstream.sh
