docs: remove Deno references from user-facing documentation

Deno is an internal implementation detail that end-users don't need to
know about. Users only interact with the probitas CLI, not the runtime.

Kept Deno requirement only for shell installer where it's a practical
prerequisite. API names like "Deno KV" and code examples remain unchanged
as they're part of the functionality users directly use.
