deduplicate cookbook

[tuttiex]

This documentation update focuses on reducing redundancy by deduplicating identical cookbook content and ensuring a single source of truth for key guides.

What changed? Why?
I removed redundant copies of
launch-tokens.mdx
and
ai-prompting.mdx
from the cookbook/ directory. These files were identical to the versions maintained in get-started/.

Why:

Single Source of Truth: Prevents documentation from diverging over time.
Maintenance: Simplifies future updates to These core guides.
User Clarity: Removes confusion about which guide is the most current.
Navigation: Updated
docs.json
so the "Cookbook" navigation points to the definitively managed versions.
Redirects: Added permanent redirects for the old paths to ensure no broken links for bookmarks or SEO.
Notes to reviewers
This PR follows the "small, focused PR" guideline from the contribution README. It focuses strictly on deduplication and repository hygiene. I have ensured that the redirects in
docs.json
follow the established project pattern.

How has it been tested?
File Deletion: Confirmed
docs/cookbook/launch-tokens.mdx
and
docs/cookbook/ai-prompting.mdx
have been removed.
Navigation Verification: Verified that
docs.json
correctly routes "Cookbook" section users to the canonical get-started/ counterparts.
Redirect Validation: Verified the redirects array in
docs.json
contains accurate source and destination paths for both deleted guides.
