Summary: UniPlanner adds a free forever plan

Why It Matters: The product is moving from a trial-only model to a "freemium" model. This lowers the barrier for new students to try the tool without needing a credit card.

What Changed:

• Added a "Free" tier that allows one syllabus upload and one course.
• Removed the specific $2.99 monthly and $9.99 semesterly price tags from the main view.
• Added a "No credit card required" promise for the free plan.
• Updated the headline to focus on "how heavy each week will feel" rather than just "importing from syllabus."
• Simplified the description of the AI coach (UniCore) to focus on avoiding "micromanagement."
• Removed the "Interactive Demo" section from the homepage.
