docs: Add SSH operations rule and deployment script

Added SSH operations guidelines to directives.md:
- NEVER use Git for Windows SSH for operations
- Use native OpenSSH or PuTTY tools (plink, pscp)
- Git for Windows SSH has compatibility issues with some servers
- Use full path to system SSH when needed

Created deploy-bat-files-to-ad2.ps1:
- Deploys DEPLOY.BAT and UPDATE.BAT to AD2
- Preserves CRLF line endings for DOS compatibility
- Verifies file content matches after copy
- Files auto-sync to NAS via AD2's scheduled task

Reason: NAS SSH authentication failed after restart, established
AD2 deployment path as reliable alternative that preserves line endings.

+- **NEVER use Git for Windows SSH for operations**
+- Use native OpenSSH (Windows 10+) or PuTTY tools (plink, pscp)
+- Git for Windows SSH has compatibility issues with some servers

 ### Security Standards
 - Never hardcode credentials
 - Never commit `.env` files
