Simpler approach - pass LD_PRELOAD directly in the shell command
instead of using a wrapper script.

Node.js spawn with detached:true may not properly pass environment
variables on some systems. Using a bash wrapper script guarantees
LD_PRELOAD is set before the game process starts.

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)

modManager.js:
- Switch from hardcoded 'junction' to dynamic symlink type based on OS (fixing Linux EPERM).
- Add retry logic for directory removal to handle file locking race conditions.
- Improve broken symlink detection during profile sync.
gameManager.js:
- Implement retry loop (3 attempts) for game directory removal in updateGameFiles to prevent EBUSY/EPERM errors on Windows.
paths.js:
- Prevent fs.mkdirSync failure in getModsPath by pre-checking for broken symbolic links.

Added a full profile system and fixed a few critical mod loading issues.
What changed
Profiles — Implemented proper profile management (create, switch, delete). Each profile now has its own isolated mod list.
Mod Isolation — Fixed ModManager so mods are strictly scoped to the active profile. Browsing and installing only affects the selected profile.
Critical Fix — Fixed a path bug where mods were being saved to ~/AppData/Local on macOS (Windows path) instead of ~/Library/Application Support. Mods now save to the correct location and load correctly in-game.
Stability — Added an auto-sync step before every launch to make sure the physical mods folder always matches the active profile.
UI — Added a profile selector dropdown and a profile management modal.
