This PR adds a reference text at the bottom of the Integrations section in docs/index.mdx that directs users to:

• The integrations docs page (https://docs.continue.dev/mission-control/integrations)

Your PR title doesn't follow the conventional commit format, but this won't block your PR from being merged. We recommend using this format for better project organization.

Examples:

• feat: add changelog generation support
• fix: resolve login redirect issue
• docs: update README with new instructions

• 📊 Better project history tracking

This is a non-blocking warning - your PR can still be merged without fixing this.

I've opened PR #9196 with a documentation improvement suggestion. The changes use Mintlify's <Info> component instead of plain text, which provides better visual presentation and consistency with other sections in the docs. 📝
