runstone 61b5e907ce fix(schema): default to public schema for PG and database for MySQL when schema is empty
When the LLM calls `list_tables` tool without a `schema` parameter, the
  backend receives an empty string. This caused PostgreSQL and MySQL
  metadata queries to return no results because:

  - PostgreSQL: `WHERE n.nspname = ''` matches nothing
  - MySQL: `WHERE TABLE_SCHEMA = ''` matches nothing

  Fix by falling back to sensible defaults:
  - PostgreSQL `list_tables`/`get_columns`: empty schema → "public"
  - MySQL `list_tables`: empty schema → database name (MySQL schema == database)
