Follow-up
openclaw doctor --fix resolves it. It re-stages the Telegram plugin deps, upgrading jiti from 2.6.x (missing dist/babel.cjs) to 2.7.0 (file present). Command works immediately after, no gateway restart needed.
Fix:
openclaw doctor --fix
Root cause: ^2.6.1 pinned to a jiti release that omitted dist/babel.cjs. 2.7.0 restores it. Worth bumping the bundled dep floor to >=2.7.0.
