Viktor Barzin eb8695743b workstation: fix setup-devvm.sh provisioner correctness (claude detect, kubelogin pin, codex auth, t3-serve dir)
- claude-code: detect via `npm ls -g` not `command -v claude` — the admin's
  personal ~/.local/bin/claude shadowed the PATH check, so the system-wide
  install never ran (/usr/lib/node_modules/@anthropic-ai empty, no /usr/bin/claude;
  fresh non-admins had no claude). Found during the devvm reproducibility audit.
- kubelogin: pin v1.36.2 instead of releases/latest/download, so two fresh boxes
  built weeks apart are byte-identical.
- /etc/t3-serve: mkdir before the token writes (install -m doesn't create the
  parent — section 8 would fail on a fresh box).
- codex shared auth: stage /opt/codex-shared/auth.json from Vault
  secret/workstation.codex_shared_auth_json (key already existed but nothing
  consumed it — was a manual step lost on rebuild), mirroring the Claude token.
