Pull request overview

This PR introduces a dedicated DuckDB connection pool for streaming query execution and wires it into both the loadable extension runtime and the edge-runtime trex_core extension.

Changes:

• Initialize a new “streaming pool” alongside the existing query executor initialization.
• Update op_execute_query_stream to acquire/release a pooled connection instead of cloning from the shared active connection.
• Update the edge-runtime lockfile to reflect the current dependency graph.
