Effect repositories to use in opencode references.

A developer has compiled a list of recommended Effect repositories for use in opencode references, including canonical sources like Effect-TS/effect and community projects such as lucas-barake/effect-monorepo and mikearnaldi/accountability. The list covers patterns for full-stack apps, ABAC policy engines, TanStack Start integration, and coding-agent architectures.
