Raw filesystem probes — root-join and delegate, nothing else.
Distinct from load: these do not clamp against root
escape, do not consult or populate the read-scope memo, and (for
read_bytes/read_text)
do not parse. They exist so that every module outside graph reaches the
filesystem through Workspace rather than holding a ReadStorage handle of
its own — see the module doc at crate::graph. A caller that needs the
clamp (any path that can originate in a document’s own metadata) wants
load instead.
