docs(architecture): add ADR-023, resolve OQ-24 — operation error schemas

Browse Source 
ADR-023 adds error_schemas to OperationSpec so operations can declare
their domain-level failure modes (FILE_NOT_FOUND, RATE_LIMITED, etc.)
distinct from protocol-level codes (NOT_FOUND, FORBIDDEN, etc.). The
call.error payload gains an optional 'details' field carrying the typed
error payload conforming to the declared schema. from_openapi/to_openapi
map OpenAPI response status codes to/from ErrorDefinitions, making the
adapter contract from ADR-017 faithful on the error axis.

Also fixes W2 (KeyVersionMismatch stale comment in encryption.md —
ADR-021 implements rotation without this variant) and W4
(derive_encryption_key_for_version missing from service.md method list).

Spec updates: operation-registry.md (OperationSpec, ErrorDefinition,
Handler error mapping, services/schema), call-protocol.md (call.error
payload, CallError, ResponseEnvelope), README.md, overview.md,
open-questions.md (OQ-24), call/README.md, encryption.md, service.md.
