fix(about): correct timeline to match real history

Public account 「AI 不止语」 actually opened end of 2026-04 (10 days ago), not 2024.

Real story is more compelling: 8 years of CSDN/Toutiao/Douyin writing -> 2025 open-source releases -> 2026-04 brand consolidation -> 2026-05 site launch.

Hero status and About header EST. dates aligned.
