Disable GitHub Actions for iOS, tvOS, and watchOS

  - Due to the poor reliability of GitHub Actions, we are disabling PR checks
    for iOS and tvOS.
  - We’ve added Scripts/test-all-platforms, which runs tests against iOS, macOS,
    and tvOS.
  - We’ve updated install-git-hooks to install test-all-actions as a pre-push
    hook

 To set up the development environment:
 
-  1. Run `Scripts/install-git-hooks` to install pre-commit hooks that automatically check code
-    formatting.
+  1. Run `Scripts/install-git-hooks` to install git hooks that automatically check code
+     formatting on commits and run comprehensive tests before pushing.
   2. Use `Scripts/lint` to manually check code formatting at any time.
+  3. Use `Scripts/test-all-platforms` to run tests on all supported platforms locally.
+
+
+## Continuous Integration
+
+DevColorExtraction uses GitHub Actions for continuous integration. The CI pipeline:
+
+  - **Linting**: Automatically checks code formatting on all pull requests using `swift format`
+  - **Testing**: Runs tests on macOS (iOS and tvOS testing are disabled in CI due to reliability
+    issues)
+  - **Coverage**: Generates code coverage reports using xccovPretty
+
+For comprehensive cross-platform testing, developers should run `Scripts/test-all-platforms`
+locally or rely on the pre-push git hook which automatically runs all platform tests before
+pushing changes.
