Add CodeCov and RTD badges to README with auto-commit workflow

[Copilot]

Adds Read the Docs and code coverage badges to README following the ezstitcher repository pattern.

Changes

• README.md: Added RTD documentation status badge and coverage badge linking to GitHub Pages coverage report
• .github/workflows/coverage-pages.yml: Enabled auto-commit step to update coverage badge on main branch pushes

Manual Setup Required

Repository description must be updated via GitHub Settings → About → Website field to include RTD link: https://polystore.readthedocs.io

This cannot be automated via code and requires repository admin access.

Badge URLs

[![Documentation Status](https://readthedocs.org/projects/polystore/badge/?version=latest)](https://polystore.readthedocs.io/en/latest/?badge=latest)

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• https://api.github.com/repos/trissim/polystore
  • Triggering command: curl -s REDACTED (http block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

Original prompt

Can you also include code cov and rtd badges in the readme? make sure the rtd workflow is setup with link in repo description too. also setup code cov with badge like with the ezstitcher repo
