schemaorg-validate 0.2.0

//! Integration tests for the `schemaorg-validate` CLI binary.

//! These tests invoke the binary as a subprocess and verify:
//! - Exit codes (0 = clean, 1 = errors, 2 = input errors)
//! - Output format correctness (text, JSON, SARIF)
//! - All CLI flags work as documented
