Refactor structure and update programs

[malgamves]

Summary

Here are a couple things I'm proposing @karllhughes

• I audited all program links (April 2026) and reorganized the README into three sections: ✅ Active, ⏸️ Paused/Closed, and ❓ Unknown/Unverified
• Moved CircleCI to Paused (confirms PR Removed CircleCI link #237, program not accepting submissions, per CircleCI employee)
• Moved Strapi to Paused (write-for-us page no longer accessible)
• Moved 7 entries with dead/unreachable links (Content Turbine, Hashnode Web3, Literally, Soshace, TechBeacon, Vonage, Webiny) to Unknown section rather than silently removing them, so contributors can verify or remove them
• Addresses the concern raised in issue Issues not Being Resolved Despite Closure #226 about stale entries causing frustration for writers

Sections

Section	Count
✅ Active	49
⏸️ Paused/Closed	2
❓ Unknown/Unverified	7

... and on the branch rename, after merging this PR I want to rename the default branch from master to main in the repo settings.

Thoughts? I also need to do another pass tbh and see what i can update
