Fix pod install: also git-pin LiveKitUniFFI 0.0.6 (LiveKit 2.15.3's SPM-only dep)

--repo-update still failed: "Unable to find a specification for LiveKitUniFFI
(= 0.0.6)". LiveKitUniFFI is genuinely NOT on the CocoaPods CDN (trunk returns
"No pod found") — it's SPM-only — but its repo ships a podspec at tag 0.0.6 with
no further deps (it just downloads its prebuilt XCFramework). So pin it to its
git tag too, alongside LiveKitClient. LiveKitWebRTC 144.x + SwiftProtobuf resolve
from the CDN. This should complete resolution and keep us on CocoaPods (no SPM
migration).
