pub fn find_task_files(start: &Path) -> Vec<(PathBuf, TaskFile)>Expand description
Search for task files from start up to the filesystem root, nearest
first. In each ancestor directory the first of tasks.md, maskfile.md,
README.md that parses to at least one task is taken. The CLI layers these
child-first, so a nearer file shadows a farther one by task name (like just’s
set fallback, letting a project inherit a baseline of tasks from a parent).
Embedders with their own project root can ignore this and call parse.
