Extract API definitions, models, and provider specifications into a standalone llama-stack-api package that can be published to PyPI independently of the main llama-stack server. Motivation External providers currently import from llama-stack, which overrides the installed version and causes dependency conflicts. This separation allows external providers to: - Install only the type definitions they need without server dependencies - Avoid version conflicts with the installed llama-stack package - Be versioned and released independently This enables us to re-enable external provider module tests that were previously blocked by these import conflicts. Changes - Created llama-stack-api package with minimal dependencies (pydantic, jsonschema) - Moved APIs, providers datatypes, strong_typing, and schema_utils - Updated all imports from llama_stack.* to llama_stack_api.* - Preserved git history using git mv for moved files - Configured local editable install for development workflow - Updated linting and type-checking configuration for both packages - Rebased on top of upstream src/ layout changes Testing Package builds successfully and can be imported independently. All pre-commit hooks pass with expected exclusions maintained. Next Steps - Publish llama-stack-api to PyPI - Update external provider dependencies - Re-enable external provider module tests Signed-off-by: Charlie Doern <cdoern@redhat.com>
