Materialize exhibits eventual consistency where a table can appear in information_schema.tables before its columns are visible in INFORMATION_SCHEMA.COLUMNS. Since readSchema fetches these in separate queries, any updateSchema() call can produce a snapshot with tables that have empty column lists, causing crashes throughout execution (e.g., see https://github.com/sqlancer/sqlancer/actions/runs/24169417215/job/70537769855). Fix this by retrying in readSchema itself until the snapshot is consistent (all tables have at least one column), so every updateSchema() call is guaranteed to return a usable schema.

Retry readSchema until it succeeds.
