v0.2.1

• Updated the README with VS Code Marketplace install instructions

v0.2.0

• dbt integration: sql/jinja-sql files inside a dbt project that contain the VISUALISE/VISUALIZE
  keyword get a "Render ggsql Visualization" run button.
  The SQL part is compiled and executed by the dbt CLI using dbt show
  and the VISUALISE part is rendered by ggsql reading that file through its duckdb reader.
• New setting: ggsql.dbtPath (path to the dbt executable, defaults to
  dbt on PATH).

v0.1.0

• Converted to a pure VS Code extension: removed the Positron language runtime,
  connection drivers, and the ggsql-jupyter kernel integration.
• Queries now run through the ggsql CLI (ggsql exec); the run button, code
  lenses, and cell keybindings all execute via the CLI.
• Generated charts are rendered with Vega-Lite in a "ggsql Results" webview
  panel beside the editor.
• New settings: ggsql.reader (data source connection string passed via
  --reader, default duckdb://memory) and ggsql.executablePath (path to
  the ggsql binary, defaults to ggsql on PATH). The ggsql.kernelPath
  setting was removed.
