Phases 1-4: full VNC client implementation

- SessionController wraps RoyalVNCKit.VNCConnection via nonisolated delegate
  adapter that bridges callbacks to @MainActor; Keychain-resolved passwords;
  reconnect with jittered exponential backoff; NWPathMonitor adaptive-quality
  hook; framebuffer rendered to CALayer.contents from didUpdateFramebuffer.
- Touch + trackpad input modes with floating soft cursor overlay; hardware
  keyboard via pressesBegan/Ended → X11 keysyms; UIPointerInteraction with
  hidden cursor for indirect pointers; pinch-to-zoom; Apple Pencil as direct
  touch; two-finger pan / indirect scroll wheel events.
- Bidirectional clipboard sync (per-connection opt-in); multi-monitor screen
  picker with input remapping; screenshot capture → share sheet; on-disconnect
  reconnect/close prompt; view-only and curtain-mode persisted.
- iPad multi-window via WindowGroup(for: UUID.self) + context-menu open;
  CloudKit-backed ModelContainer with local fallback; PrivacyInfo.xcprivacy.

10 VNCCore tests + 4 VNCUI tests pass; iPhone and iPad simulator builds clean.
