feat(juejin): add Juejin (掘金) read-only adapter (#2007)
* feat(juejin): add Juejin (掘金) read-only adapter
Two PUBLIC commands for the Juejin developer community: `recommend` (homepage feed) and `hot` (article ranking by category). Native fetch against api.juejin.cn; no browser, no auth. Category aliases (`backend`, `frontend`, `android`, `ios`, `ai`) resolve to Juejin's stable numeric ids.
Closes #1711
* fix(juejin): fail closed on API shape drift
* fix(juejin): expose recommendation cursor
* fix(juejin): classify response cursor drift
