Feature Request: Align Opus RED behavior when E2EE is enabled

Describe the problem

When E2EE is enabled in the JS SDK, Opus RED is forced off:

client-sdk-js/src/room/participant/LocalParticipant.ts

Lines 1096 to 1111 in 6b1d69c

    
           const req = new AddTrackRequest({ 
        
             // get local track id for use during publishing 
        
             cid: track.mediaStreamTrack.id, 
        
             name: opts.name, 
        
             type: Track.kindToProto(track.kind), 
        
             muted: track.isMuted, 
        
             source: Track.sourceToProto(track.source), 
        
             disableDtx, 
        
             encryption: this.encryptionType, 
        
             stereo: isStereo, 
        
             disableRed: this.isE2EEEnabled || !(opts.red ?? true), 
        
             stream: opts?.stream, 
        
             backupCodecPolicy: opts?.backupCodecPolicy as BackupCodecPolicy, 
        
             audioFeatures, 
        
           });

Android/iOS do not seem to force RED off for E2EE:
Android: https://github.com/livekit/client-sdk-android/blob/8f7a8a6d129ab1dc23f2e22d998b7498f58d8955/livekit-android-sdk/src/main/java/io/livekit/android/room/participant/LocalParticipant.kt#L459-L470
iOS: https://github.com/livekit/client-sdk-swift/blob/d1114653257df97122b565f795888db360dffbc5/Sources/LiveKit/Participant/LocalParticipant.swift#L620-L643

This inconsistency is confusing for cross-platform apps.

Describe the proposed solution

Please either:

allow RED with E2EE in JS (if feasible), or
document why RED must be disabled with E2EE and apply the same behavior across SDKs.

Alternatives considered

Keep current behavior but clearly document per-SDK differences.
