Подготовка базовой VM Tart для iOS Simulator

devops

frb-tart-prepare is a Claude Code skill that guides the preparation and explanation of the reusable Tart base VM on macOS used for iOS Simulator validation in the flutter_rust_bridge project. It points to the canonical source of truth — `tools/tart_macos/README.md` — which covers local OCI registry mirroring, Packer-based provisioning, smoke testing, promotion, and base image hygiene. The core workflow principle is to build changes into `frb-tart-base-candidate`, validate them, then promote to the immutable `frb-tart-base`; manually installing tools into a running base VM is explicitly prohibited. Durable base image changes belong in `tools/tart_macos/packer/frb-tart-base.pkr.hcl` or its provisioning scripts. This skill is intended for engineers setting up macOS CI environments with isolated virtual machines for iOS Simulator testing.
