Migrate coverage reporting from Coveralls to Codecov

[Copilot]

Replaces Coveralls with Codecov for coverage reporting, switching from xdebug to pcov and removing the php-coveralls dependency.

Changes

• .github/workflows/ci.yml — across all six PHPUnit jobs:

  • coverage: xdebug → coverage: pcov
  • Clover output simplified: build/logs/clover.xml → clover.xml (drops mkdir -p build/logs)
  • Replaced Coveralls upload step with Codecov action:

    - name: Upload coverage to Codecov
      uses: codecov/codecov-action@v5
      env:
        CODECOV_TOKEN: ${{ secrets.CODECOV_TOKEN }}

• README.md — Coveralls badge replaced with Codecov badge

• composer.json — php-coveralls/php-coveralls removed from require-dev

Original prompt

Migrate from Coveralls to Codecov for coverage reporting, mirroring the changes made in brick/math#109.

Changes required

1. .github/workflows/ci.yml

This repo has multiple phpunit jobs (phpunit-mysql, phpunit-mariadb, phpunit-postgres, phpunit-sqlite, phpunit-geos, phpunit-geosop). In ALL of them, make the following changes:

• Change coverage: xdebug to coverage: pcov in the Setup PHP step.

• In the "Run PHPUnit with coverage" step, change the clover output path from build/logs/clover.xml to clover.xml (and remove the mkdir -p build/logs line):

  - name: Run PHPUnit with coverage
    run: vendor/bin/phpunit --coverage-clover clover.xml
    env:
      # keep any existing env vars (ENGINE, MYSQL_HOST, etc.)

• Replace the "Upload coverage report to Coveralls" step with:

  - name: Upload coverage to Codecov
    uses: codecov/codecov-action@v5
    env:
      CODECOV_TOKEN: ${{ secrets.CODECOV_TOKEN }}

  (No if: condition needed since these jobs always run coverage — remove the old step that runs vendor/bin/php-coveralls with COVERALLS_REPO_TOKEN.)
