0.48.0 (2026-06-12)

⚠ BREAKING CHANGES

• ManifoldMLX and ManifoldLlama are no longer products of this package. Add the manifold-mlx / manifold-llama companion packages and register their backends via quickStart(backends:) — see docs/MIGRATION-0.48.md.
• traits: the AnyLanguageModel package trait no longer exists. Remove it from your traits: array and import ManifoldAnyLanguageModel.
• traits: the Ollama and CloudSaaS package traits no longer exist. Remove them from your traits: array; depend on ManifoldOllama / ManifoldCloudSaaS products and register what you need.
• traits: consumers passing traits: ["Voice"], ["Tools"], ["AppIntents"], or ["Skills"] (or .trait(name:) equivalents) get a resolve error — delete the trait and keep the product dependency. ManifoldSkills is no longer in the default trait set; it is re-exported unconditionally through the ManifoldKit umbrella instead.
• traits: the MCP and MCPBuiltinCatalog package traits no longer exist. Remove them from your traits: array; MCP is now always available.
