- Rewrite the feature list as comparison bullets (editable editor,
enhanced file tree, Changes / Background Tasks / Side Chat / bottom
workbench — none of which the stock sidebar has)
- Split the full release history into CHANGELOG.md / CHANGELOG_EN.md;
READMEs keep only v0.21.1 and link out
- Drop Star History; move the ecosystem section after Community
- Fix stale claims: v0.21.1 is the npm latest stable (not the alpha
channel); drop the untruthful 'built-in browser' hero badge; pin
'^0.21.1' in update / source-install notes
- Condense the install prose and the top IMPORTANT block
