Pull request overview

This PR centralizes the duplicated “job cache + pg_notify listener” functionality by moving the shared implementation into vectorize-core, and updating server and proxy to call into that shared module.

Changes:

• Added vectorize_core::cache module containing the shared job notification trigger setup, listener loop, and cache refresh/load logic.
• Updated server and proxy cache modules to delegate to (and re-export) the shared core implementations.
• Added tracing to vectorize-core dependencies to support the moved logging.
