v0.5.4

Changed

• Relicensed from Elastic-2.0 to GNU AGPL-3.0-or-later. Elastic-2.0 is not an
  OSI/SPDX-recognized license, so GitHub (and tools that key off its detection, like
  Glama) could never identify it — it showed as "Other/NOASSERTION". AGPL-3.0 is
  OSI-approved and auto-detected, and its network copyleft keeps the original intent:
  Yggdrasil stays free to use, modify, self-host, and redistribute, but anyone who
  modifies it or offers it as a hosted/network service must release their source
  under the same license.
