lineark-sdk 2.1.1

//! Online integration tests for the lineark SDK against a real Linear workspace.
//!
//! These tests require a valid Linear API token at `~/.linear_api_token_test`.
//! When the token file is missing, tests are automatically skipped with a message.
//!
//! The token should be connected to a test workspace — never use production tokens here.
