llama-swap was http-only by DSN, pushing TLS-fronted instances onto the openai:// scheme (which loses the management/image methods). Add a "llama-swaps" scheme that builds an https base URL, alongside "llama-swap" (http, local-first) — mirroring redis/rediss. Both share one factory; llama-swaps is scheme-only (no default built-in). The choice stays explicit because a DSN has no reliable http-vs-https signal.
