ScyllaDB exposes a DynamoDB-compatible API (Alternator), so Agno's existing DynamoDb class works against it by pointing a boto3 client at the Alternator endpoint. No agno code changes are required. Add a ScyllaDB storage provider tree mirroring the DynamoDB pages: - database/providers/scylladb: overview + agent/team/workflow usage - examples/storage/scylladb and examples/agent-os/dbs/scylla - reference/storage/scylladb and _snippets/db-scylladb-params - register the pages in docs.json (nav + examples + reference) - list ScyllaDB alongside DynamoDB in the provider index, storage feature table, and contents-db backend list Every page carries the mandatory Alternator write-isolation warning (--alternator-write-isolation=always or only_rmw_uses_lwt); permissive modes silently drop concurrent counter/conditional writes. A disambiguation note distinguishes this storage integration (Alternator) from the existing ScyllaDB vector-store integration (Cassandra driver). Verified with `mint broken-links` (clean).

Description
ScyllaDB exposes a DynamoDB-compatible API (Alternator), so Agno's existing
DynamoDbclass works against it by pointing a boto3 client at the Alternator endpoint.
Every page mentions the mandatory Alternator write-isolation that's needed so
concurrent counter and conditional writes aren't silently dropped
