Bump version and add compatibility note

Update manifest version to 2026.03.05 and change version_name to indicate support from 0.24.0 to the latest. Add a 2026-03-05 changelog entry in README noting forward compatibility with v0.24.0 (and inviting issues for older versions). No functional changes.

 ## 更新日志
 
+2026年03月05日 向前兼容到0.24.0,可能再往前也行,因为只测试了0.24.0和0.25.0以及当前最新版本,如有更早版本需求,可issue反馈
 2026年02月22日 由于原作者基本放弃更新,现接手维护,不兼容更新,匹配 v0.26.1 ,欢迎各位大佬PR
