Add SqliteSaver-based checkpointing so crashed analyses resume from the last successful graph node instead of restarting from scratch. - checkpointer.py: get_checkpointer(), thread_id(), has/clear_checkpoint() - --checkpoint flag (default: off for backward compatibility) - --clear-checkpoints flag to force fresh start - Per-ticker SQLite DBs for parallel worker safety - Logs 'Resuming from step N' vs 'Starting fresh' - Clears checkpoint on successful completion (no stale state) - Tests: crash resume + different date starts fresh |
