chore: transfer repo to the wardenbot-ai GitHub org (deferred)

[pardamike]

The wardenbot-ai GitHub org is secured. Moving pytest-wardenbot there gives it a company identity instead of the personal pardamike handle — cleaner and better for contributors / continuity. Deferred for now; tracking here.

Checklist when we do it:

• Transfer via repo Settings → Transfer ownership → wardenbot-ai (GitHub auto-redirects old pardamike/... URLs; clones/links keep working)
• Update the ~43 pardamike references (README badges, pyproject [project.urls], docs links)
• Re-install the Codecov GitHub App on the org (OIDC — no token needed)
• Re-add any CI secrets under the org

Notes: the PyPI name (pytest-wardenbot) is unchanged, and the docs domain pytest-wardenbot.wardenbot.ai already decouples docs from the handle. Not urgent — best done before significant inbound stars/links accumulate.
