Restructure the CI Check workflow to run unit, integration, and system tests in parallel with test splitting across 4 shards. This replaces the single monolithic `check` job with separate jobs for compilation, unit tests, integration tests, and system tests. Key changes: - Trigger on pull_request instead of push - Add compile job to warm up Gradle cache - Split integration and system tests across 4 parallel shards using donnerbart/split-tests-java-action - Add JUnit report merging jobs for integration and system tests - Add test result uploads and test reporter publishing - Add failed test annotations with xmllint - Add final check job that gates on all upstream jobs - Free disk space before integration and system tests - Update actions/checkout and actions/setup-java to latest versions
Quote all values containing `#` followed by expressions so YAML
does not interpret them as inline comments. Without quotes, names
like `Integration test results #${{ matrix.split-index }}` were
parsed as just `Integration test results`, causing all matrix shards
to upload artifacts with the same name and fail with 409 Conflict.

Separate the shared split-total into per-test-type configuration so integration tests run across 4 shards and system tests across 8.
Not needed for this project and adds unnecessary build time.
Rename the gate job name from "CI Check" to "check" so the reported status "CI Check / check" matches the existing branch protection rule.
