Fix RandomX validation exploit with difficulty reset, improve build system

- One-time difficulty reset to minimum for 17 blocks at activation height
- Separate RandomX build dirs for linux/win64 cross-compilation
- Add build target tracking to auto-clean on target switch
- Automated win64 release packaging to release-win64/
- Add build artifacts to .gitignore
- Miner memory diagnostics and large-page dataset fallback
