[Agent] Replace SideNavigationController with SwiftUI side menu container

[github-actions]

Summary

Replaces the UIKit SideNavigationController slide-out menu with PVSwiftUISideMenuContainer — a UIViewController whose side-menu overlay is implemented as a pure-SwiftUI animated panel.

What Changed

New file: PVSwiftUISideMenuContainer.swift

• PVSwiftUISideMenuContainer: top-level container that embeds the main content as a full-screen child and overlays the side menu via UIHostingController<SideMenuOverlayView>
• SideMenuOverlayView (SwiftUI): spring-animated slide panel + dimming overlay driven by PVRootViewModel.isMenuVisible
• Left-edge UIScreenEdgePanGestureRecognizer (iOS) to initiate menu open
• Tap-to-dismiss and swipe-left-to-close on the dimming overlay
• Orientation-aware menu width: 30% iPad, 70% iPhone portrait, 40% iPhone landscape
• tvOS: focus/preferredFocusEnvironments forwarding to the menu when visible; gamepad events handled by existing PVRootViewController code

Modified files:

• PVRootViewController: showMenu()/closeMenu() now only set viewModel.isMenuVisible; gamepad toggle uses viewModel.isMenuVisible instead of the old sideNavigationController?.visibleSideViewController check
• PVRootViewNavigationController: parent-type check updated from SideNavigationController → PVSwiftUISideMenuContainer
• PVAppDelegate: setupSideNavigation() replaced with setupSwiftUISideMenu() returning PVSwiftUISideMenuContainer

Deleted files (UIKit SideNavigationController stack):

• SideNavigationController/SideNavigationController.swift
• SideNavigationController/SideNavigationController+NestedTypes.swift
• SideNavigationController/UIViewController+SideNavigationController.swift
• SideMenu/SideMenuNavigationController.swift (was already mostly commented out)

Design Decisions

• SideMenuView keeps its UINavigationController wrapper (via SideMenuView.instantiate()) so the UISearchController-based search bar continues to work.
• The SideMenuOverlayView bridges the UIKit navigation controller via UIViewControllerRepresentable, allowing SwiftUI to manage the slide animation while UIKit manages the internal navigation stack.
• The overlay hosting controller starts with isUserInteractionEnabled = false and is toggled on/off via Combine subscription to viewModel.$isMenuVisible, so touches pass through to main content when the menu is closed.

Phase 2 (future)

Phase 2 (replace PVRootViewController and PVRootViewNavigationController with SwiftUI NavigationStack) is tracked in the parent epic #3601.

Part of #3601

Test Plan

• Build and run on iOS Simulator — menu slides in/out with spring animation
• Verify left-edge pan gesture opens the menu on iPhone
• Verify tap on dimming area closes the menu
• Verify swipe-left on dimming area closes the menu
• Verify gamepad menu toggle opens/closes the menu (tvOS + MFi)
• Verify menu width: ~70% on iPhone portrait, ~40% landscape, ~30% iPad
• Verify search bar in side menu still works
• Verify console navigation (shoulder buttons) still works
• Build for tvOS — no DragGesture/UIScreenEdgePanGestureRecognizer compile errors

✅ Verified: Compile / Symbol Resolution

File	Status
PVSwiftUISideMenuContainer.swift	✅ All types exist — PVRootViewModel, SideMenuView.instantiate(), UIHostingController, UIScreenEdgePanGestureRecognizer
PVRootViewNavigationController.swift	✅ parent is PVSwiftUISideMenuContainer — nav controller is embedded as a direct child so parent is correct
PVRootViewController.swift	✅ showMenu() / closeMenu() now solely driven by viewModel.isMenuVisible; old sideNavigationController?.showLeftSide() calls removed
PVAppDelegate.swift	✅ setupSwiftUISideMenu returns PVSwiftUISideMenuContainer which is returned to window setup as UIViewController

✅ Verified: No Residual References to Deleted Types

• SideNavigationController — only in comments ✅
• .sideNavigationController computed property — fully gone ✅
• SideMenuNavigationController — fully gone ✅
• showLeftSide() / closeSide() / updateSideMenuWidth() — fully gone ✅

✅ Verified: Multi-Platform Guards

• DragGesture — inside #if !os(tvOS) ✅
• UIScreenEdgePanGestureRecognizer — inside #if !os(tvOS) ✅
• childForStatusBarStyle etc — inside #if os(iOS) ✅
• preferredFocusEnvironments / setNeedsFocusUpdate() — inside #elseif os(tvOS) ✅
• Whole file wrapped in #if canImport(UIKit) ✅

✅ Verified: @ObservedObject Usage

SideMenuOverlayView uses @ObservedObject var viewModel: PVRootViewModel — correct because the view does not own the model; it's passed in from PVSwiftUISideMenuContainer. PVRootViewModel is ObservableObject. ✅

✅ Verified: DragGesture.Value.velocity

Available since iOS 17.0. Our minimum target is iOS 17+. ✅

🐛 Bug Fixed — Pushed

PVRootViewNavigationController.deinit — NotificationCenter observer leak

_initThemeListener() unconditionally adds a NotificationCenter observer, but deinit only removed it inside if #unavailable(iOS 17.0, tvOS 17.0) — a condition that is never true on our iOS 17+ minimum target. Every PVRootViewNavigationController instance leaked one .themeDidChange observer.

Fixed: removed the dead availability guard; observer is now always removed in deinit.

ℹ️ Pre-existing (Not Introduced by This PR)

• Redundant if #available(iOS 17.0, tvOS 17.0, *) inside #if !os(tvOS) in PVRootViewNavigationController — always true, harmless.
• try! Realm() in PVRootViewController:582 — pre-existing.
• Large commented-out block in PVRootViewNavigationController._initThemeListener — pre-existing.

---

Overall: PR is good to merge. One real bug fixed, all structural changes are correct.

✅ Files Reviewed

File	Status	Notes
PVSwiftUISideMenuContainer.swift	✅ Clean	New file, correct implementation
PVAppDelegate.swift	✅ Clean	setupSwiftUISideMenu correctly replaces setupSideNavigation
PVRootViewController.swift	✅ Clean	Menu toggle logic correctly uses viewModel.isMenuVisible
PVRootViewNavigationController.swift	✅ Clean	Parent type check updated, deinit guard correctly removed
SideNavigationController/*.swift (deleted)	✅ Verified	No dangling references anywhere in codebase
SideMenu/SideMenuNavigationController.swift (deleted)	✅ Verified	No dangling references

Compilation Verification

• Type safety: PVSwiftUISideMenuContainer (UIViewController subclass) properly returned as UIViewController from setupSwiftUIInterface() ✓
• SideMenuView.instantiate returns UIViewController — matches sideMenuViewController: UIViewController parameter ✓
• viewModel.$isMenuVisible — @Published var isMenuVisible: Bool exists on PVRootViewModel ✓
• DragGesture.Value.velocity — available iOS 16+, min target is iOS 17+ ✓
• No unresolved symbols from deleted files — all call sites cleaned up ✓
• @ObservedObject on SideMenuOverlayView.viewModel — correct (viewModel passed in from outside, not owned by this view) ✓

Multi-Platform Compatibility

Platform	Status	Notes
iOS	✅	Edge pan gesture, DragGesture, status bar properly included
tvOS	✅	Focus forwarding implemented; iOS-only APIs guarded with #if !os(tvOS)
macOS Catalyst	✅	No Catalyst-specific issues found

Platform Guard Audit

• UIScreenEdgePanGestureRecognizer → #if !os(tvOS) ✓
• DragGesture → #if !os(tvOS) ✓
• childForStatusBarStyle/Hidden/HomeIndicator → #if os(iOS) ✓
• childViewControllerForUserInterfaceStyle + preferredFocusEnvironments → #if os(tvOS) ✓
• UIDevice.current.userInterfaceIdiom in menuWidth() — on tvOS returns .tv (not .pad), correctly falls through to horizontalSizeClass path returning 40% width ✓

Dead Code / Unused Variables

None introduced by this PR. New code in PVSwiftUISideMenuContainer.swift:

• All properties used ✓
• All methods called ✓
• cancellables Set used by Combine subscription ✓
• overlayHostingController used in tvOS focus forwarding ✓

Pre-existing Issues (out of scope, not introduced by this PR)

• import RxSwift unused in PVRootViewController.swift — pre-existing
• extension PVGameLibraryViewController: UIDocumentPickerDelegate placed in PVRootViewController.swift — pre-existing

Conclusion

No issues introduced by this PR. The implementation is clean, type-safe, multi-platform compatible, and all deleted code has been properly removed with no dangling references. No fixes required.
