pub fn find_workspace_root(start: &Path) -> Option<PathBuf>Expand description
Walk upward from start looking for the first ancestor that
contains .memstead/workspace.toml (the post-rebuild workspace
marker). Returns the first ancestor directory carrying the marker,
or None if the walk reaches filesystem root without finding one.
Both files and directories are accepted as start. A plain file’s
parent is used as the first candidate; for a directory, the
directory itself is the first candidate.
Deeper-marker semantics: because the walk is upward and stops at the first match, an inner workspace nested inside an outer one resolves to the inner.
Mirrors memstead-mcp/src/main.rs::find_workspace_root and the
per-command walkers in memstead-cli/src/commands/link.rs /
memstead-cli/src/commands/publish.rs. Keep the resolution rules in
sync if any of these change.
