Models stage-d (default) + stage-e (next-edit companion); extension 0.6.1

- stage-d: next-line / block-close / multi-line fixes, symbols format 2, TS errors in the header.
  Held-out: 0.426 exact / 0.700 edit sim (stage-c 0.405 / 0.689); block close 0.27 -> 0.79.
- stage-e: next-edit (80% exact region rewrites, abstains on 100% of no-edit samples).
- Manifest: nextEditModel (companion) and nextEditFormat (older extensions ignore it, so they
  never use next-edit with the empty-output deletion bug).
- Daemon: next-edit served by the companion model in a second llama-server, started after the
  main model loads.
