Fix iOS app spawning and improve library management

[Xplo8E]

This commit addresses multiple issues with iOS device handling and library compilation in KnoxSpy:

1. iOS Spawn Fix (fridamanager.ts)

   • Fix iOS app spawn failure caused by passing invalid uid option
   • iOS doesn't support multi-user like Android, so spawn options now check platform before adding uid parameter
   • Only pass uid for Android devices when user is not -1
   • Updated misleading log message about "attach instead"

2. Library Compilation (server.ts)

   • Add npm install step before frida-compile to ensure @types/frida-gum and other dependencies are available
   • Use --ignore-scripts flag to skip environment-specific prepare/build hooks that may reference unavailable commands (like fridaenv)
   • Fixes "Cannot find namespace 'ObjC'" TypeScript compilation errors

3. Platform-Based Library Filtering (websocket.ts)

   • Add platform filtering to library list handler
   • Normalize "iPhone OS" to "iOS" for consistent matching
   • Backend now filters libraries by platform when requested, ensuring only compatible libraries are shown for each device

4. Frida Script Console Logging (repl.ts)

   • Add logHandler to capture console.log/warn/error from Frida scripts
   • Forward script logs to server console with [Frida Script LEVEL] prefix
   • Broadcast script logs to frontend via WebSocket (action: "script.log")
   • Enables real-time debugging and visibility into script execution

These changes enable successful iOS app spawning, proper library compilation from uploaded ZIP files, and better debugging capabilities for Frida scripts.
