Replace the Go backend with the Rust workspace and route Android/iOS through UniFFI bindings. Include the migrated extension runtime, network, providers, media metadata, downloads and library operations, with version 5.0.0+147. Remove Go sources, adapters, native build selection and CI dependencies. Build Rust unconditionally and lock the iOS Rust pod using a relative path. Retain legacy source and migration evidence in a local ignored archive. Validation: Android Kotlin compile and 53 native tests; Swift Rust-branch equivalence and syntax; CocoaPods install; workflow, shell, Ruby, plist and diff checks. Reuse the preceding 100 Rust tests, fmt/Clippy and five-ABI build checkpoint; no new APK or iOS application build for this cleanup. Known follow-up: URL/URLSearchParams globals are missing from the Rust JS runtime. A controlled extension replay confirms a URL-resolution regression; this commit does not fix that runtime gap.
