JAVA_TOOL_OPTIONS -javaagent path was not quoted, causing JVM to
truncate at first space. Affects all users with spaces in install
path (e.g. "Hytale F2P Launcher").

Fix pre-release downloads failing with "unexpected EOF" by validating
cached PWR file sizes against manifest expected sizes. Previously only
checked > 1MB which accepted truncated files. Also update Discord
invite link to new server across all files.

Migrate from downloading pre-patched server JARs from CDN to downloading
the DualAuth ByteBuddy Agent from GitHub releases. The server JAR stays
pristine - auth patching happens at runtime via -javaagent: flag.
clientPatcher.js:
- Replace patchServer() with ensureAgentAvailable()
- Download dualauth-agent.jar to Server/ directory
- Remove serverJarContainsDualAuth() and validateServerJarSize()
gameLauncher.js:
- Set JAVA_TOOL_OPTIONS env var with -javaagent: for runtime patching
- Update logging to show agent status instead of server patch count

* fix: comprehensive UUID/username persistence bug fixes
Major fixes for UUID/skin reset issues that caused players to lose cosmetics:
Core fixes:
- Username rename now preserves UUID (atomic rename, not new identity)
- Atomic config writes with backup/recovery system
- Case-insensitive UUID lookup with case-preserving storage
- Pre-launch validation blocks play if no username configured
- Removed saveUsername calls from launch/install flows
UUID Modal fixes:
- Fixed isCurrent badge showing on wrong user
- Added switch identity button to change between saved usernames
- Fixed custom UUID input using unsaved DOM username
- UUID list now refreshes when player name changes
- Enabled copy/paste in custom UUID input field
UI/UX improvements:
- Added translation keys for switch username functionality
- CSS user-select fix for UUID input fields
- Allowed Ctrl+V/C/X/A shortcuts in Electron
Files: config.js, gameLauncher.js, gameManager.js, playerManager.js,
launcher.js, settings.js, main.js, preload.js, style.css, en.json
See UUID_BUGS_FIX_PLAN.md for detailed bug list (18 bugs, 16 fixed)

Added a maxlength attribute to the player name input and enforced a 16-character limit in both install and settings scripts, providing user feedback if exceeded. Refactored modManager.js to replace symlink-based mod management with a copy-based system, copying enabled mods to HytaleSaves\Mods and removing legacy symlink logic to improve compatibility and avoid permission issues.
The bundled libzstd.so is incompatible with glibc 2.41's stricter heap
validation, causing "free(): invalid pointer" crashes.
Solution: Automatically replace bundled libzstd.so with system version
on Linux. The launcher detects and symlinks to /usr/lib/libzstd.so.1.
- Auto-detect system libzstd at common paths (Arch, Debian, Fedora)
- Backup bundled version as libzstd.so.bundled
- Create symlink to system version
- Add HYTALE_NO_LIBZSTD_FIX=1 to disable if needed

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.
