fix(ms-ai-architect): RX-P2 reg-kjede-wiring + komprehensiv agent-sti-forankring [skip-docs]

- classify->dpia->ros kjede-wiring: dpia/ros Task-templater far eksplisitte
  AI Act-klassifiserings- + DPIA-funn-felt (kjede-data agentene allerede branchet pa)
- dpia-agent uutforbar "spor bruker" -> "marker vurderingen" (Hvis-ikke-klassifisert
  + Error Handling); speilet til ros-analysis-agent
- adr-writer-agent: Write-verktoy fjernet, returnerer ADR-markdown til hovedkontekst
  (command er eneste skriver -- subagenter skriver aldri)
- KB-sti-forankring (komprehensiv): 36 bare referanse-subdir-stier i 6 agenter +
  2 commands fullkvalifisert med CLAUDE_PLUGIN_ROOT/skills/<skill>/references/ ---
  ogsa innen-skill kortformer, uresolverbare i installert modus
- mekanisme: validate-plugin.sh Check 6d (bare-subdir-lint m/ hyphen-guard) +
  negativ-probe-test (beviser tenner) + RX-P2 wiring-regresjonstester
