Add metadata for docs pages

[RishiByte]

Overview

Add page-specific metadata for important documentation pages.

Why this helps

Docs pages are easier to discover and share when each page has a clear title and description.

Suggested scope

• Review pages under project/src/app/docs.
• Add metadata exports to a few key docs pages, such as quick start, learning paths, all roadmaps, and common questions.
• Keep titles and descriptions concise.

Acceptance criteria

• Add metadata to at least 4 docs pages.
• Each metadata title is specific to the page.
• Each metadata description is clear and under roughly 160 characters.
• The project builds successfully.
