The entity-less tool pack (§5 tool-op pack seam, v3 §7 'cli / tool pack'). Bundles the `exa-catalog` ingredient and one connection-agnostic recipe — `search-web-exa` runs a `recued-core.exa.web.search` Tier-P pack op-step that binds to the bundled Exa catalog and dispatches pass-through through the D-165 gateway (read-tier, audited). Installs dormant until you enroll an Exa connection (Settings → Connections) and pick it for the recipe's `exa` variable; web egress is reachable only as this pack-bound op, never as a direct ingredient.
