Struct ChatMessage 

pub struct ChatMessage {
    pub role: String,
    pub content: String,
    pub tool_call_id: Option<String>,
    pub tool_calls: Option<Vec<Value>>,
}

OpenAI-compatible chat message.

Why: Both trusty-memory’s chat subcommand and trusty-search’s /chat endpoint speak the OpenRouter format. Sharing the struct keeps them in step (and lets callers compose chat histories without re-defining types). Tool-use additions (tool_call_id, tool_calls) follow the OpenAI function-calling shape: assistant messages set tool_calls when the model requests tool invocations; subsequent role: "tool" messages echo the matching tool_call_id with the tool’s result in content. What: role is one of "system" | "user" | "assistant" | "tool". content is the message text. tool_call_id is the id of the tool call this message is replying to (only set when role == "tool"). tool_calls is the raw OpenAI tool_calls array on an assistant message that asked to invoke tools — kept as serde_json::Value so we don’t drop any fields the upstream may add. Test: serde round-trip in chat_message_round_trips.
