integrity: add Codec[T] and CodecBuilder[T]

Introduce Codec[T] (schema-only, no storage handle) and CodecBuilder[T]
with a fluent value-receiver API mirroring TypedBuilder[T].

- Build() returns (*Codec[T], error); namer.NewLayeredNamer already
  returns an error, so bubbling it is more honest than panicking and
  matches Go conventions.
- Three separate namer instances are constructed (generator, validator,
  top-level) with signer-only / verifier-only / signer∪verifier sig
  location lists, matching today's TypedBuilder.Build() pattern and
  avoiding key-type leakage.
- Stale location-override key validation runs directly in Build()
  before calling NewLayeredNamer, so a typo like
  WithHashLocation("sah256", …) is no longer silently ignored.
- Bind is deferred to a later change to keep this one schema-only with
  no cross-package dependency.
