feat(ms-ai-architect): Spor D N1–N5 — Anthropic-deterministiske skill-sjekker (TDD) [skip-docs]

Legger de fem deterministiske sjekkene fra Anthropics «Skill authoring best
practices» som K1–K10-rubrikken manglet, i begge lag av score-motoren:

- eval.mjs (disk-laget): extractName + checkN1..checkN5
  - N1 name-validitet (≤64, a-z0-9-, ingen «claude»/«anthropic»; gerund rapporteres, gater ikke)
  - N2 description ikke-tom + ≤1024 tegn
  - N3 refs én nivå dypt (ref-fil lenker ikke til annen ref-fil)
  - N4 TOC i ref-filer >100 linjer (delpoeng = andel store filer med TOC)
  - N5 forward-slash-stier (ingen Windows-backslash-stier i body)
  wiret inn i evalSkill.deterministic (leser nå ref-fil-innhold for N3/N4)
- lib/skill-score.mjs (ren): N1–N5 i CRITERIA (vekt 1, ikke-gulv, det)

Live-sanity mot de 5 skills: N1/N2/N5 rene, N3 fanger ekte nøstet ref i
advisor (licensing-matrix.md → 3 andre ref-filer), N4 avdekker 387 store
ref-filer uten TOC (primær forbedringsspak for oppgraderingsfasen).

Tester: kb-eval 110→134 (+24). validate 239, kb-update 316 uendret grønt.
[skip-docs]: N1–N5 alt spesifisert i docs/skill-quality-scoring-plan.md §2.
