Fills in the CHANGELOG.md entry for the checkpoint-anchoring security fix,
fuzzing infrastructure and its findings, OP_RETURN/coinbase-tag decoding,
and localization fixes since 0.9.1 (see previous commits), and bumps
<Version>/versionCode across the App and Android head csproj files ahead
of the tag.
