Why

The site listed every warehouse as supported, although Snowflake is the main target and BigQuery, Databricks and SQL Server have had less production use. There was also no public roadmap for the planned UI.

Changes

• Added a short roadmap page: the self-hosted UI next, then beta warehouses to supported and more warehouses; virtual environments are not planned.
• Marked Snowflake, DuckDB, MotherDuck and PostgreSQL as supported and BigQuery, Databricks and SQL Server as beta, with the levels defined on the adapters page and a beta note on each beta adapter page.
• Listed Snowflake first on the homepage, adapters page and sidebar, added beta tags to the homepage warehouse list, and changed "Coming soon" warehouses to "Planned".

Verification

• astro build and scripts/check_links.py: 108 pages, 0 broken links.
• Checked the roadmap, adapters page and homepage warehouse list in the browser, in light and dark themes.
