Setup v7: BCQuality knowledge-mirror er maskin-lokal, ikke repo-lokal

- curabis-standard.agent.md v6 -> v7: mirror deployes til
  ~/.claude/bcquality-knowledge/ (delt af alle repoer paa maskinen)
  i stedet for .github/.agents/bcquality-knowledge/ i hvert repo
- CLAUDE.md-templaten peger paa maskin-mirroren via %USERPROFILE%
  (aldrig literal udviklersti) og faar self-heal-instruktion
- Mode B: v6-aera-oprydning (fjern committet repo-mirror, gitignore
  stien, foreslaa CLAUDE.md-migrering) + genkend hardcodede
  udviklerstier og raa-URL-lister som foraeldede CLAUDE.md-former
- sync-bcquality-knowledge.ps1: fast destination $env:USERPROFILE
  \.claude\bcquality-knowledge i stedet for $PSScriptRoot-relativ
  (det var dobbelttydigheden der skabte repo-mirrors)
- Ny regel: bcquality-knowledge-must-mirror-to-machine-not-repo
- Setup-artefakter skal fetches som raa bytes (Invoke-WebRequest
  -OutFile) - aldrig via strengindhold, som dobbelt-encoder UTF-8

Begrundelse: udviklere skifter repo mange gange dagligt; N repo-
mirrors er permanent ude af sync, een maskin-mirror kraever een
sync pr. upstream-aendring. CI/cloud-agenter henter selv reglerne
via .github/bcquality.config.yaml.
