Security: - Remove -k/--api-key CLI option (prevents process list exposure) - API key now only accepted via NREL_API_KEY environment variable Features: - Add API timeout (30s) and retry logic with exponential backoff - Add rate limit detection and graceful test skipping Documentation: - Add AGPLv3 LICENSE file - Add CONTRIBUTING.md with development guidelines - Add CHANGELOG.md following Keep a Changelog format - Add copyright headers to all source files Tests: - Expand test suite from 19 to 52 tests - Add edge case tests (negative values, boundaries) - Add input validation tests - Add financial calculation verification tests - Add rate limit handling to skip tests gracefully - Remove skip-on-failure logic - tests now properly fail All 52 tests pass (19 skipped when API rate limited). 🤖 Generated with [Crush](https://crush.cli.software) Assisted-by: GLM-5 via Crush <crush@charm.land>
