access: values sealed for their readers

cs1.<age file>: a value encrypted with age to its readers' SSH keys,
which no node decrypts. _continuum/access/sealed declares paths whose
values must be sealed, for named readers or anyone; nodes check the
recipients by age's key tags, at the API and on receipt.

Auth plan M8, reworked: sealed values instead of containers, readers
as users only (nodes hold no keys).
