Prevent premature exit in non-interactive mode when tasks pending (#216) (#217)

Detects non-interactive environments (CI, opencode run) and prevents session idle when:
- Background tasks are still running
- Incomplete todos remain in the queue

Changes:
- Add isNonInteractive() detector for CI/headless environment detection
- Export detector from non-interactive-env hook module
- Enhance todo-continuation-enforcer to inject prompts BEFORE session.idle
- Pass BackgroundManager to todo-continuation-enforcer for task status checks

This fix prevents `opencode run` from exiting prematurely when work is pending.
