[iOS] Duplicate class PodsDummy_libwebp causes crashes when using jitsi_meet_flutter_sdk

[MarcelGalster]

Description

When running the iOS app, the following warnings appears at startup, which leads to a crash:

objc[...]: Class PodsDummy_libwebp is implemented in both .../Runner.app/Frameworks/libwebp.framework/libwebp and .../Runner.app/Frameworks/JitsiMeetSDK.framework/JitsiMeetSDK.

objc[...]: Class PodsDummy_libwebp is implemented in both .../Runner.app/Frameworks/libwebp.framework/libwebp and .../Runner.app/Frameworks/GiphyUISDK.framework/GiphyUISDK.```

Root Cause

jitsi_meet_flutter_sdk ships JitsiMeetSDK.framework as a precompiled
vendored framework, which already bundles libwebp and GiphyUISDK internally.
At the same time, CocoaPods resolves libwebp as a separate standalone dynamic
framework and embeds it into the app bundle — resulting in three copies of
libwebp at runtime.

Steps to Reproduce

1. Add jitsi_meet_flutter_sdk to pubspec.yaml
2. Run pod install
3. Build and run the iOS app

Expected Behavior

libwebp should only be present once at runtime, embedded inside
JitsiMeetSDK.framework (and/or GiphyUISDK.framework).

Actual Behavior

libwebp is embedded three times:

• As a standalone libwebp.framework
• Inside JitsiMeetSDK.framework
• Inside GiphyUISDK.framework

Environment

• Flutter: 3.41.6
• jitsi_meet_flutter_sdk: ^12.0.0
• CocoaPods: 1.16.2
• iOS Deployment Target: 13.0
• Xcode: 26.4

Possible Fix

Remove libwebp from the standalone embedded frameworks, since it is already
provided transitively by JitsiMeetSDK.framework and GiphyUISDK.framework.
