The mesh's own files for a module are placed by the mesh, not the definition (issue 174)

48 definitions stop naming /var/lib/mesh/<module>: the directory says `place: "mesh"`, the two
subdirectories beneath it (gitea's runtime state, anthropic-manager's output) state their path
beneath it, and every credential, binding, merged file and mount names it as ${dir:mesh-state}.
Resolved on the default root, every definition names exactly the paths it named before —
TestPlacedDirectoriesKeepTheirPaths in mesh-controller, run over both checkouts. Needs the
controller that knows the word (mesh-controller, same branch) one release ahead.
