analyze: print next-step guidance when the database is written

When analyze finishes it prints the processed-file counts and the total time, but nothing about what to do next:

Finalizing database. Successfully processed files: 2, Failed files: 0, Files without TypeTrees: 0, Ignored files: 0

Total time: 0.256 s

In a usability experiment, an AI agent given only the binary discovered the built-in views (object_view, view_breakdown_by_type, ...) by running .tables in sqlite3 and called it "a lucky/pleasant discovery, not something --help mentioned". For someone using the downloaded binary, stdout plus the one URL in --help is the entire discovery surface.

Proposal: after finalizing, print a short next-step hint, something like:

Database written to database.db. Start with the object_view and view_breakdown_by_type views.
Schema reference: https://github.com/Unity-Technologies/UnityDataTools/blob/main/Documentation/analyzer.md

The URL should be version-pinned once the --help documentation link is (tracked separately).

Comienza en la salida de finalización del comando analyze y sigue el código que imprime los recuentos de archivos procesados y el tiempo total. Añade las indicaciones propuestas sobre la base de datos, la vista y la referencia del esquema después de escribir la base de datos; luego ejecuta analyze con una entrada de ejemplo para verificar el texto de stdout y la URL.
