Replace the GPL-3.0 license text with the full GNU Affero General
Public License v3.0 text, strengthening copyleft coverage for the
network-service use case (users interacting with Bookhoard over the
network are entitled to the corresponding source).
- LICENSE: swap GPL-3.0 text for the canonical AGPL-3.0 text (gnu.org)
- README.md: update both license references (Project Status and
License sections) from GPL-3.0 to AGPL-3.0
- docs/user/sync-guide.md: update the footer license reference
The bundled BSD 3-Clause license in internal/sevenzip/LICENSE is a
third-party dependency license and is intentionally left unchanged.
