v19: git-baseret konsumtion - forberedelse til privat repo

Beslutning: BCQuality skal vaere privat. En fork af et offentligt repo
kan ikke goeres privat, saa flyttet sker via detach/nyoprettelse - men
FOERST omlaegges al konsumtion fra tokenfri raw-URLs til git-baseret
adgang, shippet mens kanalen stadig er offentlig, saa flaaden aldrig
oplever et hul. GCM er token-haandteringen: udviklerne er allerede
autentificeret.

Kernen er KANAL-KLONEN: %USERPROFILE%\.claude\BCQuality, pinned til
stable. Alt kopieres derfra (filsystem-kopi = raa bytes; ingen
CDN-cache, ingen API-limits).

- sync-bcquality-knowledge.ps1 v2: git-baseret (klon/fetch/checkout
  stable, mirror bygges lokalt, skriver selv versionsmarkoeren)
- Install-CurabisMachine.ps1 v2: onboarding = git clone + script fra
  klonen; foerste GCM-login ER autentificeringen
- curabis-standard.agent.md v19: SRC/BASE-tokens peger paa klonen;
  fetch betyder copy; Mode B Step 0 freshener klonen; ny Mode B-
  sektion opdaterer maskin-CLAUDE.md ved konsumtionsmodel-skift
  (gated, Identity bevares); CLAUDE.md-templatens self-heals er
  git-baserede
- machine/CLAUDE.md v2: auto-update gater paa git fetch/rev-parse
  i stedet for GitHub API; setup laeses fra klonen
- Ishikawa + al-triage + Francis: fallbacks peger paa mirror/klon;
  al-triages hardcodede URL-liste fjernet (samme sygdom som Ishikawa
  havde). Aerlig konsekvens: Copilot mister live custom-fallback
- CONSUMPTION.md: Access model-sektion + to-linjers onboarding
- Invoke-CurabisEvidence: RawBase markeret legacy/doed
