fix(world): replace hardcoded path in fix_world.py with dynamic derivation

world/fix_world.py line 3 used hardcoded '/root/workspace/timmy-academy'.
Changed to use os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
to derive project root dynamically, fixing non-VPS deployments.

Closes #16
