研究方向
The issue proposes adding upload progress to the favicon but lacks a concrete design. Investigate how to dynamically update a favicon using canvas or SVG. Review the codebase for existing upload progress events (e.g., in the upload module) that can be hooked into. Look for any prior discussion in the comments that may hint at maintainer preferences. No linked PRs exist, so implementation requires starting from scratch.
