Collapse the twin DataCollectorFactory and DataPublisherFactory into a
single Factory type. RawStorage already implements both DataCollector and
DataPublisher, so the two factories were mechanically duplicating each
other; their only real difference was which integrity options
(verifiers vs signer/verifiers) the caller wired up.
Along the way drop a handful of redundant shims now subsumed by the
unified factory and RawStorage:
- CSConnection / ConnectCStorage: a duplicate codec wrapper around
RawStorage. The two failover callers now build a RawStorage
directly via NewStorage with an empty objectLocation.
- IRawStorage: declared but never used as a type.
- CreateDataCollector: a three-line wiring helper with a single
caller; inlined.
- NewConfigStorage: a one-line default-argument helper folded into
Factory.NewRemoteStorage.
Rename FileDataPublisher -> FilePublisher for symmetry with
FileCollector. Helpers in cli/cmd that constructed the two factories
are consolidated into createCollectorFactory /
createPublisherFactory / createCollectorAndPublisherFactories. The
cli/cluster/cmd nil-checking createPublisherAndCollector splits into
openRemoteCollector (show) and openCollectorAndPublisher (publish).

Drop redundant indirection across lib/cluster and lib/integrity and wire the cleaned-up API through cli/cmd: - Merge datacollector.go, datapublisher.go, errors.go into types.go; remove unused CollectEmptyError and errWrongRevision. - Inline defaultFileReadFunc and the newFileCollector wrapper. - Collapse RawStorage's collectByKey/publishByKey/collectByRange/ publishByRange into Get/Put/Collect/Publish; inline applyIntegrityBuilderOptions into NewStorage. - Wire optional cleanup into RawStorage.Close via SetCleanup so callers don't need a wrapper; drop failoverStorage. - Expose NewCollectorFactory/NewPublisherFactory in cli/cluster as a single source of truth, inline the cli/cmd/common.go delegation wrappers at the 13 call sites in cli/cmd, and wrap pass-through errors crossing the cli/cluster boundary. - Merge dummy_repository.go into lib/integrity/integrity.go; drop unused AddHash/Add stubs; shrink redundant flag-registrar tests; wrap os.Open's error in dummyRepository.Read with the path. - Annotate three RawStorage internal pass-throughs with //nolint:wrapcheck — the callee already wraps with the storage type.
