fix(docs): remove broken --index-url install claims; git+ is the only working path

[Coding-Dev-Tools]

Summary

The self-hosted PyPI index at coding-dev-tools.github.io/pypi-index/simple/ returns 404 (never deployed). Both README.md and AGENTS.md advertised pip install --index-url ... as the primary install method, which is false.

Changes

• README.md: Replace dual install instructions with the verified-working pip install git+https://github.com/Coding-Dev-Tools/apiauth.git
• AGENTS.md: Same fix — remove the dead --index-url form, note the index is not published

Verification

• Documentation-only changes (no code modified)
• Cherry-picked from existing local commits (37753d2, 79a1841) that were stranded on local master
• The git+ install path is the only working method (confirmed: the PEP-503 index 404s)
