Fix auto-install reliability and bump version to 1.2.0

- Verify tensorrt is actually importable before trusting the install marker;
  retry install if marker exists but import fails (likely cause of user reports
  where the node loaded but TensorRT did not work)
- Add --no-input to pip install calls to avoid hanging on interactive prompts
- Show pip stdout during auto-install so users can see progress
- Improve failed-install cooldown message with retry instructions
- Bump version to 1.2.0
