refactor: replace pre-patched JAR download with ByteBuddy agent

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

-**Documentations:**
-* [Hytale-Server-Docker by Sanasol](https://github.com/sanasol/hytale-server-docker/tree/main?tab=readme-ov-file#dual-authentication)
-
-**Requirements:**
-* Using the patched HytaleServer.jar
-* Has Official Account with Purchased status on Official Hytale Website.
-* This official account holder can be the server hoster or one of the players.
-
-**Steps:**
-1. Running the patched HytaleServer.jar with either [B. Local Dedicated Server](#b-local-dedicated-server) or [C. 24/7 Dedicated Server (Advanced)](#c-247-dedicated-server-advanced) successfully.
-2. On the server's console/terminal/CMD, server admin **MUST RUN THIS EACH BOOT** to allow players with Official Hytale game license to connect on the server:
-```
-/auth logout
-/auth persistence Encrypted
-/auth login device
-```
-3. Server console will show instructions, an URL and a code; these will be revoked after 10 minutes if not authorized.
-4. The server hoster can open the URL directly to browser by holding Ctrl then Click on it, or copy and send it to the player with official account.
-5. Once it authorized, the official accounts can join server with F2P players.
-6. If you want to modify anything, look at the [Hytale-Server-Docker](https://github.com/sanasol/hytale-server-docker/) above, give the repo a STAR too.
