🔧 Improvements

• Test suite: Expanded to 655 tests. Added in TimelineExportValidationTests: testFCPXMLExporterExportsClipMarkers, testFCPXMLExporterExportsClipChapterMarkers, testFCPXMLExporterExportsClipKeywords, testFCPXMLExporterExportsClipRatings, testFCPXMLExporterExportsClipMetadata, testFCPXMLExporterClipMetadataAllTypesValidatesAgainstDTD (export with all metadata types then DTD validate), testFCPXMLExporterXmlDeclarationStandaloneNo (assert exported XML uses standalone="no" for DTD/xmllint compatibility).
• PR #14 (clip-level metadata export): Test coverage for FCPXMLExporter exporting clip-level metadata (markers, chapter-markers, keywords, ratings, custom metadata) as children of <asset-clip> per FCPXML DTD; tests in TimelineExportValidationTests; Tests/README.md updated with coverage and XML declaration standalone note. Thanks @stovak!
• TimelineManipulationTests: Addressed GitHub Code Scan findings: replaced actor-based NowBox + DispatchSemaphore with a lock-based class (NSLock) to avoid thread exhaustion and deadlock risk when providing injectable "now" in timestamp tests; replaced XCTAssertNoThrow with do-catch and non-optional bindings for insertClipAutoLane and insertingClipAutoLane to properly verify success and handle thrown errors.

🐛 Bug Fixes

• xmllint / DTD validation: Resolved "standalone" warnings when validating exported FCPXML with xmllint --dtdvalid. XML declaration now outputs standalone="no" instead of removing the attribute, so libxml2 treats the document as dependent on an external DTD and no longer warns about whitespace nodes from pretty-printing. Change in XMLDocumentExtension.fcpxmlString.
