Add PocketPay Contracts issue approval readiness checklist

[El-swaggerito]

Description

Difficulty: Expert

Type: Documentation

Summary

Create an issue approval readiness checklist for PocketPay Contracts contributors.

Current Behaviour

Contributors may assume their work is complete once a PR is merged, even when tests, CI, documentation, or acceptance criteria are incomplete.

Expected Behaviour

The repo should provide a clear checklist that contributors and reviewers can use before considering an issue ready for evaluation.

Suggested Implementation

Add checklist documentation covering implementation completeness, tests, CI status, acceptance criteria, documentation, and known limitations.

Files or Areas Likely Affected

• contracts/
• src/
• tests/
• docs/
• README.md
• Makefile

Acceptance Criteria

• Approval readiness checklist is added.
• Checklist states that merged PRs are still subject to evaluation.
• Testing expectations are included.
• CI status expectations are included.
• Acceptance criteria review is included.
• README links to the checklist.

Additional Notes

This helps contributors evaluate their work before payment periods.

Hi, I'd like to apply to this issue.

I have experience writing contributor documentation and QA/review checklists for open-source repos. My approach: add a concise "issue approval readiness checklist" covering implementation completeness, test coverage, CI status, acceptance-criteria review, documentation, and known limitations, making clear that a merged PR is still subject to evaluation — then link it from the README.
