Conversation
Bumps the go directive to 1.27.0 and adds an explicit `toolchain go1.27.1` so the Gradle build (which reads the toolchain line to set GOTOOLCHAIN for gomobile) pins the latest patch release. Also upgrades golang.org/x/mobile to 20260908204917-8b95e45f8d3e and the golang.org/x modules it pulls in. No source changes required.
No source changes are required: the deprecated `network.PacketProxy` API that `intraPacketProxy` uses is still present in v0.1.0-rc1.

Why
Keeps the toolchain and dependencies current, ahead of the QUIC circumvention work. Go 1.25 is two releases behind,
golang.org/x/mobilewas last bumped in June, and the Outline SDK has a release candidate for v0.1.0.Dependency-only change; no source changes were required.
What changed
Go toolchain
go.mod:go 1.25.0→go 1.27.0, plus an explicittoolchain go1.27.1(latest patch release).Android/app/build.gradlealready prefers thetoolchainline when settingGOTOOLCHAINfor gomobile, so the build now pins the exact patch release instead of the.0release.go-version-file: go.mod, and Gradle parsesgo.moddirectly.gomobile
golang.org/x/mobile(gomobile/gobind) →v0.0.0-20260908204917-8b95e45f8d3e.golang.org/xbumps pulled in by the above:net0.56→0.59,sys0.46→0.48,crypto0.53→0.57,mod0.37→0.41,sync0.21→0.23,tools0.46→0.50.Outline SDK
golang.getoutline.org/sdkv0.0.23→v0.1.0-rc1. The deprecatednetwork.PacketProxyAPI thatintraPacketProxycurrently uses is still present in v0.1.0-rc1, so this compiles as-is. The follow-up PR in this stack migrates off it.Testing
