Subject: [PATCH 1/2] Add opt-in Skip Fuse support for Android transpilation

Gated behind SKIP_FUSE=1 so normal builds are unaffected. Skip Lite
(Kotlin transpilation) was attempted first but CoreModel's macros,
retroactive Foundation conformances, and generic initializers aren't
representable in Kotlin; Fuse compiles real Swift natively via the
Swift Android SDK, so it builds CoreModel unmodified.

Subject: [PATCH 2/2] Add CI job to build with Skip Fuse flag

Mirrors the local verification: builds the CoreModel target with
SKIP_FUSE=1 so the new opt-in Fuse dependency wiring in Package.swift
is exercised on every push.
