Run GitHub Actions on Azure Standard_F8s_v2

Azure Standard_F8s_v2 — 8 vCPU, 16 GiB RAM, x86_64. Cirun spins one up per workflow on your Azure account and tears it down when the job finishes — you pay Azure for the compute, nothing per CI minute.

Why this fits

8 vCPU and 16 GiB RAM — sized for workloads the default GitHub-hosted runners can't comfortably host, all on your own Azure account.
Compute-optimised CI when 16 GiB RAM is enough and clock is what matters.
Ephemeral by default — each job gets a clean VM, no leaked state from previous PRs.

Drop this in your repo root. The first workflow that requests the runner label spins this configuration up on your cloud account.
