Replace node-fetch with native undici for HTTP requests throughout pnpm.
Key changes:
- Replace node-fetch with undici's fetch() and dispatcher system
- Replace @pnpm/network.agent with a new dispatcher module in @pnpm/network.fetch
- Cache dispatchers via LRU cache keyed by connection parameters
- Handle proxies via undici ProxyAgent instead of http/https-proxy-agent
- Convert test mocking from nock to undici MockAgent where applicable
- Add minimatch@9 override to fix ESM incompatibility with brace-expansion
Add eslint-plugin-simple-import-sort to enforce consistent import ordering:
- Node.js builtins first
- External packages second
- Relative imports last
- Named imports sorted alphabetically within each statement
- Add currentPkg (with name/version) to custom resolver ResolveOptions
- Pass currentPkg through to custom resolvers in default-resolver
- Simplify checkCustomResolverForceResolve to use parseDepPath
