v1.0.0 — Institutional Seal Release
This release seals the shamir-cli tool as a stable, reference-grade
command-line adapter over the Shamir core and encoding layers.
No functional changes are introduced compared to v0.2.2.
The CLI behavior, flags, input/output semantics, and share formats are
considered stable and contractually defined.
Future changes are expected to be infrequent and deliberate, following
the documented versioning and compatibility guarantees.
