Summary: Riff adds IT lifecycle management features

Why It Matters: The product is moving deeper into enterprise territory by addressing long-term maintenance and IT approval hurdles. This helps them move past the "pilot" phase into permanent company use.

What Changed:

• Updated the "IT sets the rules" section to include approval workflows, maintenance, and lifecycle management.
• Changed the "Business sets the goal" description to focus on business setting problems rather than leaders defining them.
• Added a new tagline: "Generate fast. Operate for years."
• Clarified that IT oversight continues at scale to keep teams confident.
