access: what a node holds alone by `_continuum/local/<node ID>/<name>`
Setting a node's log filter took `write` on `_continuum`, all of the protocol data:
whoever could change one node's logging could change the swarm's members, remakes and
users too. Now what a node holds alone has paths of its own for capabilities, under
`_continuum/local/<node ID>/`: `log` (`/admin/log`), `config` (`/admin/config`) and
`debug` (`/debug`, always `write`), `read` to look and `write` to act
(`api::access::needed`, which takes the node's ID). So `_continuum/local/<node ID>` is
everything on one node, `_continuum/local/*/log` the log filter on every node, and
holders of `_continuum` keep it all.
Nothing is stored there: the store refuses writes under `_continuum/local`, and the
rules refuse a change touching it, as for epoch metadata. The quarantine stays with
`_continuum`: its entries are everyone's writes, which a node-local capability
mustn't show.
