Persistence:
- one delivery state per sink, with claim, crash recovery, and index replacement
- retention for delivered and dead records
- LMDB writes moved off the event loop
Pipeline:
- one attempt per dispatch, with the next try scheduled by next_retry_at
- backpressure through max_queue_size
- reload re-reads YAML; SIGTERM drains and SIGHUP reloads
Plugins:
- journald source, enricher and filter processors, Loki sink
- built-ins register when entry points are missing
API and CLI:
- health, metrics, per-sink queue, and dead-letter replay
- startup prints the pipeline on one line
Tests:
- dispatch, plugins, metrics, CLI, and persistence coverage
