Module hook 

Session-lifecycle hooks — Postgres-style phased.

The trait expands the legacy before_query / after_query shape to phased hooks at parse / analyze / plan / execute_start / execute_end / before_commit / after_commit / abort. Each phase has a default no-op implementation so existing hooks that only override the legacy methods continue to work.
