fix: add timestamp-based staleness detection for pipeline states

Closes #676, fixes #650

- is_pipeline_complete: stale if >24h old
- is_pipeline_running: stale if >6h old (likely crashed)
- reset_stale_states: purges stale entries at scheduler start
- --status shows (stale) indicator for outdated states
