Contract

• assert //go:embed dir silently excludes dotfiles, underscore files, and subdirectories containing only excluded files
• assert fs.ReadDir on embedded directory lists only non-hidden entries and omits dotfiles, underscore files, and hidden-only subdirectories
• assert all: prefix opts in to embedding dotfiles and underscore files recursively
• assert explicitly naming a dotfile in //go:embed embeds it without all: while omitting sibling files
• assert wildcard on directory matches direct files including dot and underscore files
• assert embed.FS preserves directive path prefix and fs.Sub roots the sub-filesystem
• assert scalar string and byte slice types embed single file contents directly
• assert embed.FS files implement io.Reader, io.Seeker, and io.ReaderAt, but not io.Writer
