Update documentation for the published 0.1.3 release

[tpn]

cuPhoton 0.1.3 is on PyPI, but the README, installation guides, changelog, and citation still describe it as unpublished. Update those pages, lead with a GPU-and-visualization pip install, and distinguish the available wheels from local Conda build tooling. Keep the source checkout instructions for development and repository examples, and include Python development headers in the ARM64 Photutils requirements.

Validation: repository commit hooks (including mypy and the lock check), GitHub Markdown rendering, and an independent review of the seven-document diff passed.
