 // Vendor of this package

+// ============================================================================
+// CI/CD Build Number Injection (IONOS Nextcloud Workspace)
+// ============================================================================
+// Injects a 5th element into the $OC_Version array from the .buildnumber file.
+// This file is automatically created by the CI/CD pipeline (build-artifact.yml)
+// and contains the GitHub workflow run ID for traceability.
+//
+// NOTE: This is an IONOS-specific customization for Nextcloud Workspace.
+//       It is not part of upstream Nextcloud and is used for tracking
+//       IONOS Nextcloud Workspace builds in production environments.
+//
+// @since 31.0.8
+//
+// Purpose:
+//   - Track which specific CI/CD run produced this artifact
+//   - Enable direct linking to workflow logs and build details
+//   - Distinguish between different builds of the same version
+//   - Support debugging by identifying exact build in production
+//
+// File Format:
+//   .buildnumber - Single line containing an integer (GitHub run ID)
+//   Example: 12345678901
+//
+// Result:
+//   Without .buildnumber: $OC_Version = [31, 0, 8, 1]
+//   With .buildnumber:    $OC_Version = [31, 0, 8, 1, 12345678901]
+//
+// Accessed via:
+//   - ServerVersion::getBuildId() -> 12345678901
+//   - ServerVersion::getHumanVersion() -> "31.0.8 (12345678901)"
+//   - ServerVersion::getVersion() -> [31, 0, 8, 1, 12345678901]
+//
+// Workflow URL Construction:
+//   https://github.com/{org}/{repo}/actions/runs/{buildId}
