sanasol 4c059f0a6b fix: Steam Deck/Ubuntu crash with jemalloc allocator

Root cause: glibc 2.41 has stricter heap validation that catches a
pre-existing race condition triggered by binary patching.

Changes:
- Add jemalloc auto-detection and usage on Linux
- Add auto-install via pkexec (graphical sudo prompt)
- Clean up clientPatcher.js (remove debug env vars)
- Add null-padding fix for shorter domain replacements
- Document investigation and solution

The launcher now:
1. Auto-detects jemalloc if installed
2. Offers to auto-install if missing (password prompt)
3. Falls back to MALLOC_CHECK_=0 if jemalloc unavailable

Install manually: sudo pacman -S jemalloc (Arch/Steam Deck)
                  sudo apt install libjemalloc2 (Debian/Ubuntu)

Steam Deck / Linux Crash Fix

SOLUTION: Use jemalloc ✓

The crash is caused by glibc 2.41's stricter heap validation. Using jemalloc as the memory allocator fixes the issue.

Install jemalloc

# Steam Deck / Arch Linux
sudo pacman -S jemalloc

# Ubuntu / Debian
sudo apt install libjemalloc2

# Fedora / RHEL
sudo dnf install jemalloc

Launcher Auto-Detection

The launcher automatically uses jemalloc when installed. No manual configuration needed.

To disable (for testing):

HYTALE_NO_JEMALLOC=1 npm start

Manual Launch with jemalloc

cd ~/.hytalef2p/release/package/game/latest

LD_PRELOAD=/usr/lib/libjemalloc.so.2 ./Client/HytaleClient --app-dir /home/deck/.hytalef2p/release/package/game/latest --java-exec /home/deck/.hytalef2p/release/package/jre/latest/bin/java --auth-mode authenticated --uuid YOUR_UUID --name Player --identity-token YOUR_TOKEN --session-token YOUR_TOKEN --user-dir /home/deck/.hytalesaves

Debug Commands (for troubleshooting)

Base Command

cd ~/.hytalef2p/release/package/game/latest

GDB Stack Trace (for crash analysis)

gdb -ex "run --app-dir ..." ./Client/HytaleClient

# After crash:
bt
bt full
info registers
quit

Test glibc tunables (alternative fixes that didn't work reliably)

Disable tcache:

GLIBC_TUNABLES=glibc.malloc.tcache_count=0 ./Client/HytaleClient ...

Disable heap validation:

MALLOC_CHECK_=0 ./Client/HytaleClient ...

Binary Validation

file ~/.hytalef2p/release/package/game/latest/Client/HytaleClient
ldd ~/.hytalef2p/release/package/game/latest/Client/HytaleClient

Hex Dump Commands

# Search for hytale.com UTF-16LE
xxd ~/.hytalef2p/release/package/game/latest/Client/HytaleClient.original | grep "6800 7900 7400 6100 6c00 6500 2e00 6300 6f00 6d00"

Test Different Patch Modes

# Restore original
cp ~/.hytalef2p/release/package/game/latest/Client/HytaleClient.original ~/.hytalef2p/release/package/game/latest/Client/HytaleClient
rm ~/.hytalef2p/release/package/game/latest/Client/HytaleClient.patched_custom

# Test UTF-16LE mode
HYTALE_PATCH_MODE=utf16le HYTALE_AUTH_DOMAIN=sanasol.ws npm start

# Test length-prefixed mode (default)
HYTALE_AUTH_DOMAIN=sanasol.ws npm start
