Pull request overview

This PR updates the PHP SDK release metadata and build/test configuration (version bump to 4.5.0, PHP/runtime constraints, dependency updates, and CI matrix adjustments).

Changes:

• Bump SDK/package version from 4.4.1 to 4.5.0 (Constants, composer.json, README).
• Tighten PHP requirement to ^8.1 and update dependency constraints (notably google/protobuf and phpseclib/phpseclib).

The PR title/description says it adds support for extraction_image_ids on PageResponse, but the diff only updates versions/dependencies/CI and does not modify src/DocScan/Session/Retrieve/PageResponse.php (or any parsing/tests) to expose that field. Please either include the missing PageResponse changes + tests, or update the PR metadata to match what’s actually being changed here.

php requirement is being tightened from supporting PHP 7.4/8.0 to ^8.1 only. This is a breaking change for consumers pinned to older runtimes, but the package version is only bumped from 4.4.1 to 4.5.0 (minor). If this project follows semantic versioning, this should be a major version bump (or the breaking support drop should be handled/released according to the repo’s documented versioning policy).
