"""BetterContext-to-Codex wake dispatcher bundled with the plugin.
This process runs on the machine that owns the destination Codex tasks. It
polls the shared BetterContext relay table and submits pending messages with
``codex queue``. Delivery attempts are tracked in a machine-local SQLite
database outside the plugin package. Each edition has its own host state.
