docs: render architecture & flow diagrams as draw.io charts

Replace ASCII-art diagrams across the README and docs/ with editable .drawio sources plus exported PNGs, so the diagrams render clearly in rendered markdown and can be maintained/regenerated instead of being hand-edited as fragile text art. Non-diagram blocks (code, folder trees, UI wireframes) were left as text.

-  → N failures (≥ FailoverRetryCount) → switch to other endpoint

 - **Round-robin**: primary → backup → primary → backup. No preferred endpoint after first failover — the connection stays on whichever endpoint is working.
 - **No auto-failback**: The connection remains on the active endpoint until it fails.
