fix: Enhance Lossless Scaling Frame Generation (LSFG) integration (prevent freeze, save storage space)

[joshuatam]

Description

• Update LSFG Vulkan layer to v1.3.3, improve layer stability and prevent freezes in external mode
• Move LSFG layer .so file from assets to jniLibs, treating it as a native library.
• Prevent post-install cloud save synchronization and container creation for the Lossless Scaling utility app (App ID 993090) as it does not manage game saves.
• Optimize Lossless.dll discovery by directly searching Steam install paths, bypassing container creation for the utility app, also check and delete existing created container to save storage space

Summary by cubic

Updates the Lossless Scaling Frame Generation integration to v1.3.3, bundles the Vulkan layer as a native library, and stops creating/syncing a Steam container for app 993090 to improve stability and avoid external‑mode freezes. Previously we copied the layer from assets and created a container with post‑install cloud save sync; now we load from jniLibs, read Lossless.dll directly from Steam paths, skip container/sync, and remove any existing container.

• Moves liblsfg-vk-layer.so to jniLibs/arm64-v8a; LsfgVkManager copies from applicationInfo.nativeLibraryDir, while keeping the manifest in assets with a patched library_path.
• Skips post‑install cloud save sync and container creation for Lossless Scaling (App ID 993090) in SteamService; emits PostInstallSyncStatusChanged(false) and fixes the container ID format to STEAM_993090.
• Discovers Lossless.dll by scanning SteamService.allInstallPaths using the app’s installDir, with a fallback directory search; deletes any existing STEAM_993090 container to save space.

^{Written for commit 7129761. Summary will update on new commits.}

📝 Walkthrough

Walkthrough

Lossless Scaling now installs the LSFG native library from the application library directory, searches Steam paths for its DLL, removes obsolete containers, and skips post-install cloud-save synchronization.

Changes

Lossless Scaling lifecycle

Layer / File(s)	Summary
Update native runtime installation app/src/main/java/app/gamenative/utils/LsfgVkManager.kt	The bundled LSFG runtime updates to v1.3.3-android-arm64-v8a. Installation copies the native library from nativeLibraryDir and reports missing libraries.
Manage DLL discovery and containers app/src/main/java/app/gamenative/utils/LsfgVkManager.kt	DLL discovery searches all Steam installation paths and fallback subdirectories. Existing Lossless Scaling containers are removed before installation and cleaned up through ContainerManager.
Skip utility cloud-save synchronization app/src/main/java/app/gamenative/service/SteamService.kt	Lossless Scaling skips post-install cloud-save synchronization and emits a completed non-syncing status event. Other applications retain the existing flow.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🔵 Low · up to 71297

The change avoids creating new containers for Lossless Scaling and attempts to remove existing ones, but cleanup may miss containers using the STEAM_993090 identifier, leaving bounded storage waste. The PR is mergeable with explicit owner awareness or a follow-up cleanup fix.

flow to search for the standard STEAM_ prefixed container ID first, using the
existing LOSSLESS_SCALING_APP_ID value. Preserve compatibility by falling back
to the bare app ID when no prefixed container is found, then continue deleting
