Nightly Build / build (push) Canceled after 2m36s
The tool was a single-user leftover: it only implemented the context-free
execute, so a relative path resolved against the server process cwd and
projects/{owner}/{slug}/... failed with "Cannot read file" while every
other fs tool worked. It now overrides run_with like its siblings:
memory paths outline the note from the right pool, physical paths go
through the shared UserFs shuttle (home, shared, projects, container),
and the agent-visible path is what headers and errors show. Also gains
target_path and a workspace-aware path description.
