v0.2.1 — Complete CLI, Canonical FORMAT=2, and Contract‑Level Tests
This release finalizes the command‑line interface and supporting
infrastructure while preserving the cryptographic and data contracts
introduced in v0.2.0.
Version v0.2.1 delivers a fully operational, audit‑ready CLI with
explicit split and recover workflows, canonical FORMAT=2 share
serialization, strict error handling, and comprehensive end‑to‑end
integration tests. Architectural boundaries between the CLI,
format layer, utilities, and cryptographic core are now formally
defined and enforced.
No breaking changes are introduced. All existing data and guarantees
remain valid.
