frozenMap only blocked the Map's own mutators, so
catalog.roles.get("editor").push("*") escalated a role to a full wildcard
past an error string claiming the catalog is frozen after boot; the same
applied to permission/attribute metadata objects and binding arrays.
mergeCatalogs now stores frozen copies of each, so the original declaring
module's objects are never mutated either.
Also corrects two docstrings (codegen.ts, the design doc) that claimed
`wrnexus authz generate`'s output makes a permission typo a type error —
can(), guardPermission(), and decideFor() all take a bare string and nothing
consumes the generated union automatically. Documents what it actually is:
a Permission/Role union to type your own helpers/constants against. Also
adds a README note on the subject.id contract (must be a non-empty string;
owner() compares with Object.is).
