[$25 BOUNTY] [Markdown] Add CI status badge and project shields

[cuentaprueba244w-dotcom]

Bounty: $25 (LT)

Area: README.md - project badges

Current state: README lacks CI status, code style, license, and stack badges.

What's needed: Add shields.io badges for build status, code style, license, and primary stack in a centered row at the top of README.md.

Acceptance criteria:

• At least 4 badges in a single row
• Each badge links to a valid shield target
• Consistent flat-square style

Required validation:

• Run python3 build.py
• Include the generated diagnostic .logd artifact from diagnostic/build-XXX.logd in the PR; also include diagnostic/build-XXX.json if present
• Use .github/pull_request_template.md for your submission

I’m taking this one now and will submit a scoped PR with the required diagnostics.

I would like to work on adding CI status badges and project shields to README.md.

Plan:

1. Review current README.md
2. Add shields.io badges for:
   • Build status
   • Code style
   • License
   • Primary stack
3. Use flat-square style
4. Place in centered row at top of README
5. Run python3 build.py and include diagnostic artifacts
