refactor(modules): drop loldle variants, semantle, doantu and dead framework surface

Removes six modules (loldle-ability/emoji/quote/splash, semantle, doantu)
and prunes the framework deps that were only there to serve them:

  - ai.Embedder + Client.Embed + embeddingModel const (semantle only)
  - Deps.Embedder + BuildOptions.Embedder
  - Deps.Env + Build(env) param + ModuleEnv config field + PHOW2SIM allowlist (doantu only)
  - internal/champname package (loldle now owns its lookup helpers directly)
  - template.yaml: Phow2simAPIURL parameter + PHOW2SIM_API_URL Lambda env

Active catalog: util, misc, wordle, loldle, lolschedule, twentyq, trading.

go build / vet / test all pass.
