v0.1 — connectors + quickstart

First public release of the AgentData public repo.

Included

• connectors/relational/ — on-prem connector for PostgreSQL, MySQL, SQL Server, and
  SQLite. Reads registered data sources (read-only) and/or writes flow staging
  databases (write/admin), reaching them locally so raw data and credentials never leave
  your network. Per-OS installers (macOS / Linux / Windows) included.
• connectors/PROTOCOL.md — the connector ↔ backend job contract (build your own
  connector in any language).
• QUICKSTART.md — connect a database and run your first flow.

How it connects
Outbound HTTPS poll only — no inbound port, works behind NAT/firewalls. The connector
authenticates with a one-time token (rotatable from the UI) and reports the database
engine it serves.
