v0.17.2

Changed

• [Infrastructure] Bump Fly.io VM to shared-cpu-2x / 512 MB — doubles memory headroom and burst CPU credits. The previous shared-cpu-1x / 256 MB sized warm-idle around 150 MB, leaving ~50 MB of headroom that a single active session could exhaust under non-pushdown DataFusion execution (cross-datasource joins, json_length / json_keys UDFs). The spike-then-throttle pattern under heavy queries is reduced (longer burst window before kernel CFS throttling kicks in) but not eliminated — moving to performance-1x would be required to remove burst-credit throttling outright.

Docs

• [Docs] README points at unversioned screenshot filenames — image links no longer go stale across releases.
