Deploy: RP loops (no single-shot) + confirm DOSBox needs no bundled DLLs

- net-boot/loop_rp.bat: GO.BAT-style netnub loop for RP (mirror of loop.bat,
  retargeted to rpl4opt). deploy/net_rp.conf.tmpl now calls it instead of the
  single-shot netnub + DOS pause -- the deployable runs in a loop until the
  supervisor kills DOSBox (per operator: no single-shot in the product).
- DLL closure resolved: dosbox-x.exe is a 182MB STATIC build -- import table is
  only Windows system DLLs, delay-import table empty, libpng/SDL/zlib embedded.
  Nothing to bundle; wpcap.dll comes from the Npcap install. package.ps1's "no
  DLLs" case is now informational, and the plan/README note the static build.
