Master's suite has failed 19 tests since eb6136b turned on .withErrors() in the tests (they pass on v6.5.0). This brings it back to green, one cause per commit:

• "crawl directory with options" lost its const files = await api[type]() line in that edit, so both API types threw files is not defined.
• "do not add a separator if path already ends with one" (4a2a6b3) calls normalizePath without importing it.
• The shared symlink fixtures held a broken link (fileSymlink2 → a missing file), which the tests silently skipped while errors were suppressed. With .withErrors(), every test crawling /some/dir or relative/dir threw ENOENT on it. The link is gone from the shared fixtures, and a broken link now has tests of its own, for both API types: listed by name when symlinks are not resolved, skipped when they are, and reported when .withErrors() is on.
• "crawl all files and invert path separator" fails on Linux and macOS because of a real bug, not the test. The walker reads the disk through the output path, so a \\ separator reaches readdir (ENOENT: scandir 'node_modules\'); the test only passed before because the error was suppressed and an empty result satisfies every(). The test is marked test.fails on POSIX only, since on Windows a / separator still works, with a comment saying why. A separate PR fixes the walker, which keeps native paths for the file system, and removes the marker.
