Discussion: Deprecate Vercel hosting due to rate limiting

[luojiyin1987]

Context

Vercel has implemented rate limiting on their free tier, which affects the availability of GitHub Readme Stats cards for many users.

Problem

• Users experiencing rate limit errors on Vercel-hosted instances
• Self-hosting requires additional infrastructure knowledge
• Many users just want to use the cards without deploying their own instances

Proposed Solution

Promote self-hosting options via GitHub Actions:

1. Static SVG generation - Generate cards as SVG files in the repo via Actions
2. No external services - Use GitHub's own file hosting
3. Scheduled updates - Auto-update every 6 hours or on demand

Alternatives Considered

• Migrate to Render (already supported via render.yaml)
• Migrate to other hosting platforms
• Keep Vercel as primary, add documentation for alternatives

Action Items

• Add migration guide from Vercel to GitHub Actions
• Update documentation to recommend GitHub Actions for new users
• Consider deprecating official Vercel instance
• Add example workflows for common use cases
