/**
 * Drop-in axios method wrappers with retry built in.
 *
 * Use these instead of `axios.get` / `axios.post` for outbound HTTP calls in
 * action files. The retry policy lives in `./retry.ts`.
 *
 * Why a wrapper instead of `retry(() => axios.get(...))` at each callsite?
 * TypeScript's control-flow narrowing (e.g. after `if (!env.url) return [];`)
 * doesn't propagate into nested closures, so inline `retry(() => axios.get(env.url))`
 * makes `env.url` `string | undefined` again. Passing the URL as a function
 * argument keeps the narrowing intact.
