feat(auth): add init GitHub token support across Node CLI

[calchiwo]

Implement init GitHub authentication across the CLI.

Users can now configure a GitHub token once via explainthisrepo init, enabling:

• private repository access

• higher API rate limits

• consistent behavior across Python and Node

Changes

• Auth model

• Added GitHub token prompt to Node init

• Token is stored in config under [github]

• Removed need for CLI token flags

Runtime behavior

GitHub client now resolves token from:

1. config ([github].token)

2. environment (GITHUB_TOKEN, GH_TOKEN)

Repo reader

• Fixed nullable file content handling

• prevents runtime crashes when file fetch returns null

Result

• Python and Node CLIs now share the same auth model

• Single setup path (init) for all users

• Cleaner CLI surface (no token flags)

• More reliable repo parsing

Notes

• Existing users without config will continue to work for public repos

• Private repos require running explainthisrepo init or setting GITHUB_TOKEN
