Merge origin/master (v0.5.75) into gitea/new_feature

Resolve conflicts:
- package.json / cli/package.json: take 0.5.75
- .gitignore: union both sides (upstream 9router-*/temp files + local state dirs)
- CHANGELOG.md: keep both blocks, v0.5.75 above v0.5.70
- nonStreamingHandler.js: merge imports (unwrapClineEnvelope +
  tokensForDetail/shouldPersistRequestDetail); drop dead appendRequestLog
- providers/[id]/page.js: union useState blocks (compatible-model states
  + importingClineModels)
