/**
 * metadata-manager.ts
 *
 * Responsible for persisting and loading test intent data and healing logs
 * to/from the artifacts directory on disk.
 *
 * A "TestIntent" is the canonical representation of what a test should do —
 * its name, URL, and ordered list of natural-language steps. Intents are saved
 * when a test is first generated and loaded again at execution time.
 *
 * Healing logs capture what happened when a step failed and how it was (or
 * wasn't) repaired, giving developers a history of locator drift over time.
 *
 * Role in the overall flow:
 *   generate_test → save_test → MetadataManager.saveIntent()
 *   execute_test  → MetadataManager.loadIntent()
 *   heal_test     → MetadataManager.saveHealingLog()
