This release contains the following breaking API changes: * refactor!: Pass the Codespaces body types by value and rename them to `...Request` (#4540) BREAKING CHANGE: `CreateCodespaceOptions`, `CodespaceCreateForUserOptions`, `UpdateCodespaceOptions` and `PublishCodespaceOptions` are renamed to `CreateCodespaceRequest`, `CreateCodespaceForUserRequest`, `UpdateCodespaceRequest` and `PublishCode

## What's changed - Changed auto mode for Claude API and Enterprise users, and on Bedrock, Vertex, Foundry and gateways, to default to the server-side classifier, which does not charge for classifier overhead (`CLAUDE_CODE_AUTO_MODE_SERVER=0` opts out on Bedrock, Vertex, Foundry and gateways); warns on billed fallback.

Breaking Changes: * `no_flowlib` option is removed. Use `builtin_lib=flowlib` (default) or `builtin_lib=prelude` instead. Likely to cause new Flow errors: * Render types no longer accept exact react element as arguments. See https://flow.org/en/docs/react/render-types/ for supported cases * Flow will now always infer a react jsx element to be a render type if it's an element of a component-syntax
