Greptile Summary

Updated email footer social media links to use local redirects (sim.ai/discord, sim.ai/x, sim.ai/github) instead of direct external URLs to improve email deliverability.

Changes:

• Modified email-footer.tsx to route X, Discord, and GitHub links through baseUrl redirects
• Added three new redirect rules in next.config.ts with permanent: false for temporary redirects

Rationale:
According to Resend's deliverability insights, having email links share the same base URL improves deliverability by reducing the number of external domains in emails.

Confidence Score: 5/5

• This PR is safe to merge with minimal risk
• The changes are straightforward and well-justified: email footer links now route through local redirects instead of direct external URLs. The implementation is clean with proper use of temporary redirects (permanent: false) for social media links that may change. No logical errors, security issues, or breaking changes introduced.
• No files require special attention
