/**
 * Core connector service: connects to the BlueBubbles REST server on a macOS
 * host, registers the `bluebubbles`/`imessage` message-connector pair, and
 * turns inbound webhook events into agent message memories.
 *
 * Inbound `new-message` webhooks are gated by DM/group allowlist policy, mapped
 * to entity/room UUIDs, persisted, then dispatched through the runtime message
 * service; outbound sends, reactions, edits, and unsends resolve a chat GUID via
 * BlueBubblesClient. Multi-account aware — binds to the resolved default account
 * (see accounts.ts). Phone/email handles are normalized before use.
