v0.4.0

Added

• Commits are SSH-signed when the hub supplies a signing key, so they show as verified on GitHub. (#181)

Changed

• A node now enrols to your account rather than to a node group, and serves every repository in it. (#182)
• The hub requires node 0.4.0 or newer; older clients are refused with an upgrade message. (#182)

Removed

• The legacy SKAKEL_* environment variable aliases and the ~/.skakel state directory fallback. (#181)
• A node still holding its identity in ~/.skakel mints a new one and must be enrolled again. (#181)

Fixed

• A commit is never signed with the host's own key, even where git is configured to sign by default. (#181)
• A repository's configured commit author and committer are applied instead of being ignored. (#181)
• dahrk doctor and dahrk preflight resolve the state directory the same way the node does. (#181)
• An installed node reports its real version instead of 0.0.0. (#182)
