CLI bridge: connect to iLink Hub as a virtual-token backend and run a local command per text message.
Supports single-profile YAML (flat command / args) or multi-profile YAML
(profiles + routing: fixed or prefix).
Database persistence layer.
Uses sqlx with runtime driver selection via DATABASE_URL:
sqlite:~/.ilink-hub/ilink-hub.db → SQLite (default, file created if missing)
postgres://user:pass@host/db → PostgreSQL
mysql://user:pass@host/db → MySQL
Redact a virtual token for logging: show only the first 8 characters followed by ….
This lets operators correlate log lines without exposing the full credential.
Safe against UTF-8 byte boundary panics.
