chore(swabble): stop tracking Package.resolved clobbered by Xcode resolution (#100961)

Xcode syncs the iOS project supergraph pins (ElevenLabsKit, WebRTC, cmark,
swift-markdown) into the local swabble package's Package.resolved on every
resolve, leaving permanent dirty-worktree noise. Match the existing
OpenClawKit convention: ignore the file. Reproducibility is unaffected -
swabble's only runtime dependency is exact-pinned (Commander 0.2.2) and CI
cache keys hash Package.swift + Sources, not this file.
