[v0.1.0] CLI: Support fetching issue directly from GitHub

[Kavirubc]

Problem Statement

Currently the process command requires a local JSON file path via --issue. Users should be able to process an existing GitHub issue by ID.

Proposed Solution

Support --repo owner/name --number 123 flags in process.go.
If these flags are present, fetch the issue using the GitHub client before starting the pipeline.

Feature Scope

• CLI

Hi @Sachindu-Nethmin,

I'm assigning this to you.

Thanks.

Hi @Sachindu-Nethmin,

Maybe this feature should be,

1. User inputs "I'm getting this error XX" in natural language and the fetch should be able to retrieve the issues related to that through the CLI
2. Do issue filtering and sorting through natural language.

Regardless of the use case we need to implement Pagination properly, otherwise it will use much more resources when working with repos with 1000s of error.

Plan this feature and let me know how you want to proceed before implementation.

Thank you.
