Supports Docker Compose cp - archive streams for stdin-to-service and service-to-stdout copies by staging tar streams through the compose layer and existing Apple path-copy APIs. Pins stephenlclarke/containerization@79b675d so the runtime carries the apple/container#1927 copy lifecycle regression coverage from apple/containerization#799. Upstream scan found no direct Docker Compose copy-stream PR to import; adjacent Apple work reviewed: apple/container#963, apple/containerization#652, apple/container#1832, apple/container#1905. Release-Highlight: Support Docker Compose cp - archive streams for stdin-to-service and service-to-stdout copies; includes apple/container#1927 copy lifecycle fix via apple/containerization#799.

Summary
--inputpaths direct to avoid unnecessary copying./dev/fd/<n>, and archive copy behavior.Root cause
container image load --input /dev/fd/Naccepts a path that is only meaningful in the CLI process. The image service process cannot reopen that caller-owned descriptor, so the load fails before it can consume the archive.Fixes #1429.
Validation
swift build --target ContainerCommandsswift format lint --recursive Sources/ContainerCommands/Image/ImageLoad.swift Tests/ContainerCommandsTests/ImageLoadTests.swiftgit diff --checkI also ran
swift test --filter ImageLoadTests, but this local environment fails before the filtered test target runs because the active developer directory is Command Line Tools and the test build cannot importTesting/XCTest.BUILDING.mddocuments Xcode 26 as the required active developer directory.
