feat: output sinks (Hazelcast + ClickHouse)

- SinkConfig: unified config for both sinks
- HazelcastSink: ExF map writes for market snapshot + per-asset
- ClickHouseSink: exf_data table with flattened schema, buffered inserts
- OutputSinkManager: unified manager for both sinks
- Per-spec Section 13: market_update_interval_seconds=60, asset_update_interval_seconds=5
- clickhouse-connect + hazelcast-python-client dependencies
- All 46 core NLP tests pass
