Add the linesweeper 0.5.0 package to vendor/ with no file changed, so that a fix to it can reach the Craft apps through this repository without waiting for a linesweeper release. The GitHub repository its manifest names is archived, and its README says development moved off GitHub. Leave out the test font (fonts live in craft-fonts), the logo artwork, the snapshot images and the package's repository tooling. SOURCE.json lists each with its hash. Add a workspace exclude, a [patch.crates-io] entry, SOURCE.json with the archive hash and per-file hashes, NOTICE and ATTRIBUTION.md rows, and the package's tests in the backend test script. craft-prepress's flatten feature now builds against the copy, so Cargo.lock drops the package's registry source and checksum.
