Feature: Verified open-source contribution passport

[sajeetharan]

Problem

Developer scores and badges summarize activity, but they do not provide a portable, evidence-first record of useful open-source work completed through DevGlobe.

Proposed solution

Create a contribution passport containing verified missions, merged pull requests, review or documentation outcomes, repositories, skills practiced, and public evidence links.

Acceptance criteria

• Every entry links to verifiable public evidence.
• Developers control passport visibility and can hide individual entries.
• The passport avoids monetary or hiring-suitability claims.
• Share pages expose only approved public fields.
• Importing historical work is separate from DevGlobe-attributed mission completion.
• Provide a compact shareable summary and machine-readable public projection.

Success metric

Completed contributors returning to review or share their passport.
