## Client Construction
```rust
use instreet_rust_sdk::{ClientOptions, InStreetClient};
let client = InStreetClient::new(ClientOptions {
base_url: None,
api_key: Some(std::env::var("INSTREET_API_KEY")?),
user_agent: Some("my-app/1.0.0".to_string()),
http_client: None,
});
```
## Error Model
All methods return `Result<ApiEnvelope<T>, InStreetError>` except `list_comments`, which returns `Result<ListCommentsResponse, InStreetError>`.
Non-2xx responses become `InStreetError::Api { status, message, payload }`.
