Azure OpenAI requires strict message sequencing where assistant messages with tool_calls must be immediately followed by all corresponding tool responses before any user messages can appear. This change: - Adds provider parameter to transformMessages() for provider-aware handling - Implements reorderMessagesForAzure() that buffers user messages appearing between tool calls and their responses, flushing them only after all pending tool responses are received - Applies reordering ONLY for Azure provider, not affecting other providers - Adds comprehensive tests for various Azure message ordering scenarios This is a properly scoped fix for PR #14, containing only the Go code changes without any package.json or metadata modifications.

Claude Agent SDK keeps trying to send reminder messages as to the llm, which are also in between tool calls. OpenAI has a strict policy of only tool responses allowed after tool execution. This causes system crash. We've added filtering and buffering to catch these before they get sent to openai directly or via Azure.
