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
* test: move expect blocks (without other changes) to end of test
This is required for the refactor in the next commit. The log statements
have to run before consuming the output stream, otherwise the output
stream will be empty.
* test: fix swallowed Jest expect errors in `default-reporter` package
* test: fix expected to match actual values in default-reporter tests
* refactor: remove redundant `.pipe(take(1))`
With the refactor to use `firstValueFrom`, the `take(1)` is now
redundant in many places.
```ts
firstValueFrom(output$.pipe(take(1)))
```
```ts
firstValueFrom(output$)
```
