v0.1.0

• Initial release: data-only OpenAPI request-case generators with a fail-closed
  schema support matrix, PSR-17 materialization of OpenAPI 3 parameter styles
  and JSON bodies, and pre-transport validity oracles.
• Ten constructive negative categories with misuse metadata and
  misuse-preserving shrinking.
• Framework-neutral ContractSuite: explicit operation selection, a double
  opt-in for unsafe methods, transports, credentials selection, no-5xx checks,
  opt-in RejectionPolicy, and a redacted curl reproducer.
• OperationProperty/OpenApiOperations runner surface working unchanged
  under Testo and PHPUnit 11.5–13, with PROPERTY_RUNS/PROPERTY_SEED/
  PROPERTY_DB environment parity.
