Supported migrations: v2->v3, v3->v4\n```\n\n**NoPath (no migrations registered):**\n```\nCannot migrate from schema v1 to v4. No migrations registered.\n```\n\n**MigrationFailed:**\n```\nMigration v2->v3 failed: {reason}\n```\n\n**InvalidVersionRange:**\n```\nInvalid version range: source (5) must be less than target (3)\n```\n\n### Tests Added\n- `test_no_path_error_message` - Verifies full error format with available migrations\n- `test_no_migrations_registered_error_message` - Verifies error when registry is empty",
