Created technical design documentation for the MDM profile installation feature implemented across the previous 11 commits in this PR.

Changes

  • Design Document: Added MDM_PROFILE_INSTALLATION_DESIGN.md covering:
    • Architecture and component design for MSIDWebviewTransitionCoordinator, navigation action system, and response handlers
    • Sequence diagrams for seamless embedded webview ↔ ASWebAuthenticationSession transitions
    • iOS 18+ HTTP header propagation (x-intune-url, x-intune-token) implementation details
    • Special URL pattern handling (msauth://installProfile, msauth://profileInstalled)
    • Security model (ephemeral sessions, token handling, URL validation)
    • Testing strategy and error handling flows

Context

The feature enables MDM profile installation during OAuth flows without interrupting authentication state. When the server redirects to msauth://installProfile, the embedded webview suspends (UI hidden, state preserved), launches ASWebAuthenticationSession for profile installation, then automatically resumes on completion via msauth://profileInstalled callback.

The design document provides technical reference for the ~2800 line implementation spanning 38 files, including the generic transition coordinator pattern reusable for any ASWebAuthenticationSession flow.
