setup-corepack

Setup Node package manager

Enables Corepack based on the packageManager field in package.json, and reshims asdf if present.

Purpose

• Reads package.json and enables Corepack when packageManager is set (for Yarn, pnpm, or Bun).
• Installs Corepack if it is missing.
• Runs asdf reshim nodejs when asdf is available so new shims are ready for later steps.
• No-op when package.json is missing or packageManager is empty.

Run after checkout; run before installing dependencies.
