Module table 

Lookup table trait and configuration. Lookup table trait and configuration types.

A LookupTable provides synchronous key-value access for enriching stream events via lookup joins. The trait is Send + Sync so tables can be shared across operator instances in a thread-per-core runtime.

Lookup Flow

1. Stream event arrives at a lookup join operator
2. Operator calls get_cached (Ring 0, < 500ns)
3. On cache miss, calls get (may hit disk/network)
4. Result is joined with the stream event
