Fix dev server hang by reducing log spam and event frequency (#828)

* Changes from fix/dev-server-hang

* fix: Address PR #828 review feedback

- Reset RAF buffer on context changes (worktree switch, dev-server restart)
  to prevent stale output from flushing into new sessions
- Fix high-frequency WebSocket filter to catch auto-mode:event wrapping
  (auto_mode_progress is wrapped in auto-mode:event) and add feature:progress
- Reorder Vite aliases so explicit jsx-runtime entries aren't shadowed by
  the broad /^react(\/|$)/ regex (Vite uses first-match-wins)
