Describe the bug

When attempting to launch Minecraft using Sinytra Connector with the TweakerMore Fabric mod, the game fails to load because MixinExtras (version 0.3.0 or later) is not detected in the environment. TweakerMore declares MixinExtras as a required dependency, but Sinytra Connector does not seem to provide it or correctly expose it to the mod loading process. As a result, the Connector environment incorrectly reports MixinExtras as missing, even though the modpack is otherwise valid on a normal Fabric client. This prevents the game from starting.

Steps to reproduce

1. Prepare a Minecraft runtime that launches via Sinytra Connector (Connector acting as the Fabric-to-Forge bridge / loader).
2. Add TweakerMore (tweakermore) v3.27.1 to the mods folder (or add it to the mod list in your launcher profile).
3. Do not install MixinExtras (or install no MixinExtras / an older version < 0.3.0).
4. Start the game through the Sinytra Connector profile.
5. Observe that the game crashes at startup during mod loading / initialisation. The launcher shows a mod loading failure with a suggestion to install mixinextras 0.3.0 or later, and the game does not progress past the loading screen.

Additional context

Notes

• The crash happens immediately on startup (before the main menu) and prevents the game from loading.
• Expected behaviour: TweakerMore should either load successfully if MixinExtras is provided by the environment, or Connector should surface an explicit dependency resolution path (e.g., install/forward MixinExtras) instead of failing silently.
• Please attach latest.log or the full crash/report log when investigating. A short log excerpt containing the failure message (TweakerMore requires version 0.3.0 or later of mixinextras) is helpful.
• If helpful, I can also provide the full client startup log that shows the exact failure message.
