CBGPU v0.1.0

Source release of the CBGPU school platform. See CHANGELOG.md for changes,
README.md for features and verification scope, and docs/DEVELOPMENT.md for the
credential-free local demo. Production installation requires separate backend,
DNS, secrets and equipment setup.

The source archive includes license notices. web-sbom.cdx.json inventories the
installed production npm dependencies of the web component; it is not a complete
inventory of host software, Docker images, Dart or Python packages. Validate
asset integrity with sha256sum -c SHA256SUMS.

Original code is Apache-2.0 except separately licensed components, including the
AGPL LaTeX integration. Android binaries use separate android-vX.Y.Z releases.

CBGPU Android 1.0.7

Signed Android release. See CHANGELOG.md and README.md for verification scope.
