OpenSquilla 0.5.0 Preview released

🦐 OpenSquilla 0.5.0 Preview 1 is an early look at the upcoming routing and managed-execution line. It is a preview build — try it alongside your stable install.

🧠 Model Ensemble Routing — the headline feature fans difficult turns across multiple candidate models, progressively reveals useful results while the ensemble settles, and falls back to the direct single-model path when that is the better fit. Ensemble timeout tuning keeps slow candidates from holding up a turn. In internal hard-turn evals, ensemble routing beat single-model baselines, including Fable 5.

🛡️ Managed execution & sandbox — clearer authorization behavior, better diagnostics, and gateway lifecycle conflict reporting.

🖥️ Desktop & Control UI polish — router and provider settings, drag-and-drop attachments, image preview, settings restore, and session recovery all improved.

⌨️ OpenTUI preview & terminal reliability — stronger terminal behavior, Windows process cleanup, and gateway diagnostics. A privacy switch (OPENSQUILLA_PRIVACY_DISABLE_NETWORK_OBSERVABILITY=true) can disable non-user-initiated network observability before startup.

Upgrading from 0.4.1: close any running app or gateway, install the preview, and restart. Existing config and session data are preserved. No Windows portable build is published for 0.5.0 previews — use the desktop installer or the wheel.
