dartway_offline_server 0.1.0

Server-side signed manifest primitives for DartWay offline packages.

Changelog

0.1.0

• Adds canonical Ed25519 signing primitives for generic offline package manifests.
• The signing frame itself — domain separator, schema version, algorithm name, length-prefix framing — comes from dartway_offline_shared, so the signing and the verifying half cannot drift apart.
• Manifest v2 signs an optional absolute leaseValidUntilUtc; applications retain ownership of access categories and duration policies.
