test(ms-ai-architect): Sesjon 23 — auto_discover stale-felt assertion korrigert (søk-verifisert, 13/13) [skip-docs]

Oppgave 0 (#44): søk-først (claude-code-guide mot offisiell docs) verifiserte at
`auto_discover` IKKE er et gyldig Claude Code plugin.json-felt — auto-discovery er
implisitt default (code.claude.com/docs/en/plugins-reference; ukjent felt gir kun
valideringsadvarsel, ikke feil). → stale konvensjon, IKKE manglende felt.

- tests/test-plugin-discovery.sh: stale hard-assertion (krevde `auto_discover: true`)
  → optional-felt-logikk som speiler validate-plugin.sh (fravær = PASS «auto-discovery
  implisitt»; present må være true). plugin.json URØRT (la IKKE til ugyldig felt).
  12/13 → 13/13.

validate 239/0 (ingen regresjon). STATE oppdatert: NESTE = C1 Tier 2.
