fix: remove unreal target to prevent orphaned module references

The 'unreal' target in game-bridge package.json was causing Parcel to
generate a separate entry point (2OIXX) that referenced module 'aBo8e'
without including its definition in the bundle. Removing the unreal target
ensures Parcel generates a single, complete bundle with all module
dependencies properly resolved.
