CLI 4.193.2

This patch fixes a crash that could interrupt tuist generate --binary-cache while fetching cached artifacts. The crash happened when the shared URLSession was repeatedly invalidated even though the HTTP settings had not actually changed, causing later cache downloads to fail with “Task created in a session that has been invalidated”. The CLI now only invalidates the shared URLSession when HTTP settings change, and the cache downloader resolves that session lazily so it tolerates any legitimate reconfiguration.
