feat/23-colprof
Add the Stage 4/5 native workflow: deterministic colprof/applycal/iccgamut and profcheck argv builders, verification history with CSV export and drift analytics, user/system ColorSync profile installation, and the matching SwiftUI views and fixture-driven tests. All Argyll interaction remains AGPL-isolated via ProcessManager subprocesses.
