Fix Pretext client island: inlined greedy layout, avoid slice/import issues

- Greedy line breaking inlined (avoids 3-arg slice browser issue)
- Manual word extraction via for-each+append! instead of slice
- Browser load-sxbc: handle VmSuspended + copy library registry exports
- TODO: Knuth-Plass on bytecode VM when define-library export propagation
  is fixed (compiler strips library wrapper → STORE_GLOBAL works, but
  import OP_PERFORM suspends before sync_vm_to_env copies globals)
