Pull request overview

This PR extends Docker/Compose integration by allowing the Docker watcher to automatically derive a Compose file path from native Docker Compose labels, reducing the need to set dd.compose.file manually.

Changes:

• Add compose-native discovery via dd.compose.native/wud.compose.native (and watcher-level composenative) to derive compose file paths from com.docker.compose.project.{working_dir,config_files}.
• Improve dockercompose trigger handling for digest-pinned images and expand related test coverage.
• Update API/router tests and tighten Vitest coverage thresholds.

Missing test coverage for multiple config files scenario. The implementation includes a comment "first file wins" when multiple files are present in com.docker.compose.project.config_files, but there's no test case verifying this behavior. Consider adding a test case with 'com.docker.compose.project.config_files': 'docker-compose.yml,docker-compose.override.yml' to ensure only the first file is used.

Missing test coverage for the wud.compose.native fallback label. While the integration tests cover dd.compose.native, there's no test verifying that wud.compose.native works as a fallback when dd.compose.native is not set. This is important because the label constants define both variants and getLabel is used to check both.

Suggested change

	test('getComposeFilePathFromLabels should use wud.compose.native as a fallback when dd.compose.native is not set', () => {
	const composeFile = testable_getComposeFilePathFromLabels(
	{
	'com.docker.compose.project.config_files': ' , , ',
	'wud.compose.native': 'true',
	},
	false,
	);
	expect(composeFile).toBeUndefined();
	});
