Production hardening: REAPER all-in-one launcher, rdpthread UX, logic fixes

- Add REAPER.bat single entry (pip, dirs, smoke test, launch); MASTER/MASTERSTER shim to it
- bruteforce: rdpthread helpers, safe writer close, spray_all_hosts incremental writes, progress
- gui: credential banner, spray messaging without spam; cmdkey TERMSRV host
- scanner: adaptive progress; proxy: retry cap on open_connection
- ip_utils: /32 CIDR, count_ips aligned with large dash ranges
- README/install/run: deployment docs and REAPER.bat references
