fix: remove --reload from run.sh (breaks stderr capture), fix reason/reflect level to INFO

- run.sh: removed --reload flag from uvicorn — reload subprocess breaks
  the 2>&1 pipe and all JSON logs from superset_tools_app are lost.
  Added comment with alternative for hot-reload.
- core/logger.py: reason() and reflect() now use self.info() instead of
  self.debug() — per molecular CoT protocol these are INFO-level bonds.
  DEBUG is reserved for high-frequency loops only.
