LRGEX-Compress Files

✨ New Feature: Split Compress

Right-click any folder → LRGEX → Split Compress

• Choose segment size in MB (quick picks: 50, 100, 700, 4G)
• Produces MyFolder.part001.zgx, .part002.zgx, etc.
• Each part has a SHA256 trailer for integrity verification
• Extract ANY part → auto-detects and extracts the full archive
• Corrupt part → clear error naming which part to redownload
• CLI: --split [--size <MB>] <folder>

🔧 Fixes

• Auto-update fix: write-lock released before launching installer (fixes "process cannot access the file" on some systems)
• Overwrite confirmation prompts added for both compression and extraction
• Partial files cleaned up if extraction fails or is cancelled
• Symlink targets validated inside archives before extraction
• Read-only files no longer block overwrite (atomic rename clears the attribute)
• Extraction continues past locked files instead of aborting
• Multi-volume RAR crash fixed (unrar callback)
• Crash handler added (VEH writes backtrace to crash-log.txt — no more silent crashes)
• --help flag added
• "Don't ask again" for declined updates (per-version skip)
• Temp files use unique names to prevent collisions between same-name files
• Archive bit and other Windows attributes preserved exactly on round-trip

🔒 Security

• Auto-update works for all install types (per-user, Program Files, choco, GitHub)
• Truncation check allows 64KB slack for zstd/tar trailing buffers
• Part discovery uses globbing (survives user renaming of parts)
• Contiguity check: missing middle part detected before extraction
• MAX_PARTS lowered to 1000 (bounds resource usage)
