What
Introduces a baseline of unit tests for the library's pure, dependency-free helpers, plus one mocked-network test, and makes CI actually run the test suite.
Tests added (46 assertions across 6 files)

The repo had a single existing test file and CI never ran tests. This establishes a fast, mock-light safety net over the most testable logic and ensures tests gate PRs.
