Feature idea: Add a command to fetch problem solutions/editorials

[priority3]

Background

leetgo is a fantastic tool for pulling problems, generating skeleton code, testing locally, and submitting — essentially covering the full solve-and-submit workflow.

However, one thing I often find myself doing after solving (or getting stuck on) a problem is switching to the browser to read the official editorial or top community solutions. It would be great if leetgo could streamline this step as well.

Proposal

Add a new command (e.g. leetgo solutions <problem> or leetgo editorial <problem>) that fetches and displays solution content directly in the terminal. Possible scope:

• Official editorial — the article provided by LeetCode under the "Editorial" tab.
• Top community solutions — highest-voted solutions from the "Solutions" tab, optionally filtered by language.

The output could be rendered as Markdown in the terminal, or simply printed as plain text.

Why

• Keeps the entire workflow inside the terminal without context-switching to a browser.
• Pairs naturally with the existing pick → test → submit flow — after submitting, you can immediately review better approaches.
• LeetCode exposes editorials and community solutions via its GraphQL API, so the data is accessible.

Open Questions

1. Should this be a standalone command or a flag on an existing command (e.g. leetgo info --solutions)?
2. Should it require the user to be logged in (some editorial content is premium-only)?
3. Any concerns about LeetCode ToS when fetching editorial content programmatically?

Would love to hear thoughts from the maintainer and community. Happy to help with implementation if there is interest!
