Add Screenpipe affiliate program

[louis030195]

Adds Screenpipe's public affiliate program to the registry.

Evidence:

• Program and exact commission terms: https://screenpipe.com/affiliate
• Direct application page: https://partners.dub.co/screenpipe/apply
• The public page states 25% of the first paid transaction only, with no recurring commission. Free signups may be tracked as leads but do not earn commission.
• The application page confirms the program is application-based and managed through Dub.

Fields not published publicly, including cookie duration and minimum payout, are intentionally omitted.

Local validation:

• npm run registry:build
• npx tsx scripts/verify-programs.ts screenpipe
• Signup URL classified confirmed_affiliate

Closing as superseded by #89, which contains the current validated Screenpipe program entry. Sorry for the duplicate.
