Subagent file-report note now distinguishes zero-directory runs from restricted-but-listed file access
When a subagent (a Claude Code task delegated to a separate agent) finishes, its tool results include a note about which files it's allowed to claim as its own work. This note now has different wording depending on the situation: if no save directories are configured at all, it says the subagent produced "no files during this run"; if saves are restricted but some files are still trustworthy, it now says the subagent may claim "only the files this note lists or counts."
This makes the file-attribution note more precise, so it's clearer whether a subagent had no file output at all versus limited, specifically listed file output.
