Claude (Anthropic) operations

Runtime-only provider over the Anthropic Messages API. Auth: x-api-key + anthropic-version. Messages runs are synchronous; getRun/cancelRun return the client-remembered terminal status via SynchronousRunStore. Supports the batch surface over Anthropic Message Batches.

Capability (CLAUDE_RUNTIME_SUPPORT): runs ✅ · getRun ✅ (client-local) · cancelRun ✅ (client-local) · streamRun ✅ · batch ✅.
