dbmeta v0.7.0

go get github.com/xo/dbmeta@v0.7.0

This is a v0 release, so the API can still change.

What is new since v0.6.0

• The Cassandra dialect is cassandra, and it was cql (D196). The driver
  moved from github.com/xo/cql to github.com/xo/cassandra v0.1.0, and dburl
  v0.47.0 renamed its scheme. ScyllaDB shares the dialect and the model. The
  test module requires dburl v0.47.0, and dbrun gives the tests
  DBMETA_CASSANDRA.
• The Cassandra and ScyllaDB entries print the cassandra:// URL as their
  dsn, which the new driver requires, and they make an ordinary user,
  dbmeta_user, with parity recorded for it (D195).
• Elasticsearch, Solr and OpenSearch read the release with SELECT version()
  since dbimp v0.15.0, and every user can read it, because the entries grant
  cluster:monitor/main (D191, D192). SurrealDB reads it the same way.
• Snowflake has parity for three principals, a conformance target, and a run
  of ChangePassword with seven hostile passwords (D193).
• GizmoSQL and Avatica are models (D187, D186). OpenSearch 2.19.6 answers
  Columns (D189). No model is built for Pinot, DynamoDB, VoltDB, H2, chai, csvq
  or the hosted services other than Redshift and Snowflake (D184, D185, D188,
  D194).

How it was tested

• All checks of the Test workflow passed in CI on abe2ca1, the commit this
  release is tagged on.
• Cassandra 3.11, 4.1 and 5.0, and ScyllaDB 2025.1 and 2026.3 were run live on
  the new driver.
