deploy-to-cloud-engine

Deploys a built Internet Computer project to a user's cloud engine (an OpenCloud engine): verify the icp CLI, link the console identity with icp identity link web (origin defaults to https://opencloud.org; a delegation handoff covers sandboxes whose 127.0.0.1 callback the browser cannot reach), run icp deploy against the engine's subnet, tag canisters with __META_* env vars for a named console app with labelled canisters and icon, and bake version metadata (service:git:sha, service:version) into the wasm. Also covers a funded proxy canister for cross-subnet cycle-bearing calls (exchange-rate, threshold ECDSA/Schnorr, vetKD). Use when shipping to a cloud engine; on mention of OpenCloud, an engine subnet id, or linking the icp CLI to an engine console; when sign-in never completes from a sandboxed agent; when naming, adding an icon, or recording the deployed version/git commit of a console app. Do NOT use for a general mainnet deploy with no engine or subnet (use icp-cli) or for writing canister logic.
