fix(run): S10 del 2 — post-mortem: stopp-artefakt, SDK-isolasjon, raw-JSON-direktiv

Transkript-analyse av den stoppede live-kjøringen (10 kall, 162 250 tokens,
$0.331506): konfig-lekkasjen (setting_sources=None laster ALLE filsystem-
settings) injiserte operatørens Claude-konfig i hvert kall — ~10-15k uncachede
tokens, en påtvunget bekreftelses-preamble som gjorde ren-JSON-svar umulige,
og en checker kapret av lekkede instrukser (debatt konvergerte aldri).

- persist_stop_artifacts: stopp-event verbatim + usage/kost persisteres ALLTID
  ved BudgetExceeded (delt usage-shape med fullført-run-stien)
- build_call_options: setting_sources=[] (SDK isolation mode, verifisert mot
  installert 0.2.110-kilde), system_prompt=None → tom system-prompt; detach-
  bevis via monkeypatchet query
- _generation_prompt: krever ONLY the raw JSON object (fence-innpakning ga
  4 fullpris parse-retries)

187/187 uten nøkkel · ruff + mypy --strict rene · tre detach-bevis RØDE → grønn
