When replacing domain strings with shorter ones, the replaceBytes function
was only copying the new bytes without clearing the leftover bytes from
the old pattern. This caused "free(): invalid pointer" crashes on Steam
Deck and Ubuntu due to corrupted string metadata in the .NET AOT binary.
Fix: Fill the entire old pattern region with 0x00 before writing the
new bytes. This ensures no leftover data remains that could corrupt
the binary structure.

- Introduce DualAuthPatcher with support for hybrid authentication
- Update default auth domain to `auth.sanasol.ws`
- Integrate Java detection and bundled JRE handling for patcher execution
- Add server patch flag for avoiding redundant patching
- Automate DualAuthPatcher setup: download, compile, and execute with dependencies
- Enhance patching logic for extended logging and modularity
- Add support for domains from 4 to 16 characters
- Domains <= 10 chars: direct replacement, subdomains stripped
- Domains 11-16 chars: split mode (first 6 chars -> subdomain prefix)
- Add length-prefixed byte format encoding for client binary
- Verify binary contents when checking if already patched
- Detect file updates and archive old backups with timestamps
- Fallback to legacy UTF-16LE format for older binaries
- Update patcher version to 2.0.0
Based on patching approach from Mollomm1/Hytale-EMULATOR
