Ari rewrite

[semperos]

Rewrite of Ari.

• Uses Goal's supported CLI harness. Cobra and Viper dependencies removed.
• Removes DuckDB dependency (will probably add back later given how versatile DuckDB itself is); includes SQLite at this point (smaller footprint)
• Adds Fyne GUI library as a dependency
• Ports some of ari's definitions, but not all
• More comprehensive http client implementation
