feat: bump majordomo + support llama-swap(s) provider spellings

- Bump majordomo to the latest build (...225659).
- Accept every llama-swap spelling in gadfly's endpoint switches —
  "llama-swap"/"llama-swaps" (mirroring majordomo's DSN schemes: http vs
  https TLS) plus the un-hyphenated "llamaswap"/"llamaswaps" — in both the
  GADFLY_PROVIDER+GADFLY_BASE_URL override and the
  GADFLY_ENDPOINT_<NAME>="llama-swap|url[|key]" form. Previously only the
  un-hyphenated "llamaswap" matched, so a majordomo-canonical "llama-swap"
  hit "unknown provider".
- The LLM_* DSN path (llama-swap:// / llama-swaps://) already works via
  majordomo.Parse — no gadfly change needed there.
- README providers table + error messages updated; new endpointProvider
  alias tests.

gofmt clean, go vet quiet, go test -race green.
