Shopfloor imaging: CMM type, Configure-PC override fix, serial drivers

- CMM imaging pipeline: WinPE-staged bootstrap + on-logon enforcer
  against tsgwp00525 share, manifest-driven installer runner shared via
  Install-FromManifest.ps1. Installs PC-DMIS 2016/2019 R2, CLM 1.8,
  goCMM; enables .NET 3.5 prereq; registers GE CMM Enforce logon task
  for ongoing version enforcement.
- Shopfloor serial drivers: StarTech PCIe serial + Prolific PL2303
  USB-to-serial via Install-Drivers.cmd wrapper calling pnputil
  /add-driver /subdirs /install. Scoped to Standard PCs.
- OpenText extended to CMM/Keyence/Genspect/WaxAndTrace via
  preinstall.json PCTypes; Defect Tracker added to CMM profile
  desktopApps + taskbarPins.
- Configure-PC startup-item toggle now persists across the logon
  sweep via C:\\ProgramData\\GE\\Shopfloor\\startup-overrides.json;
  06-OrganizeDesktop Phase 3 respects suppressed items.
- Get-ProfileValue helper added to Shopfloor/lib/Get-PCProfile.ps1;
  distinguishes explicit empty array from missing key (fixes Lab
  getting Plant Apps in startup because empty array was falsy).
- 06-OrganizeDesktop gains transcript logging at C:\\Logs\\SFLD\\
  06-OrganizeDesktop.log and now deletes the stale Shopfloor Intune
  Sync task when C:\\Enrollment\\sync-complete.txt is present (task
  was registered with Limited principal and couldn't self-unregister).
- startnet.cmd CMM xcopy block (gated on pc-type=CMM) stages the
  bundle to W:\\CMM-Install during WinPE.
