test: making tests faster

[omercnet]

This pull request restructures the integration test suite and CI workflow to improve test execution speed and maintainability while respecting Descope API rate limits. The main changes include partitioning integration tests into separate XUnit collections and CI jobs for parallel execution, updating test attributes for flexible filtering, and revising documentation to reflect the new approach.

Test organization and parallelization:

• Partitioned integration tests into five XUnit collections (Authentication Tests, User Management Tests, Tenant Management Tests, Authorization Tests, and Project & Settings Tests) to allow parallel execution of non-conflicting tests, while maintaining sequential execution within each collection. Each test class is now assigned to the appropriate collection and marked with a [Trait("Category", ...)] attribute for CI filtering. (Descope.Test/IntegrationTests/IntegrationTestCollection.cs, all test files) [1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11] [12] [13] [14] [15] [16] [17] [18]

• Updated the CI workflow to split testing into three jobs: build, unit-tests, and integration-tests, with the latter running in parallel by test category using a matrix strategy. Build artifacts are shared between jobs to avoid redundant builds. (.github/workflows/ci.yaml) [1] [2]

Documentation updates:

• Revised RATE_LIMITING.md to document the new partitioned collection strategy, trait-based filtering, and the impact on test execution times and rate limiting. (Descope.Test/IntegrationTests/RATE_LIMITING.md) [1] [2]

Pull request overview

This PR restructures the integration test suite to enable parallel execution while respecting Descope API rate limits, resulting in a 2-4x speedup in CI. Tests are partitioned into 5 independent collections that can run simultaneously, with sequential execution preserved within each collection to avoid resource conflicts.

Key changes:

• Partitioned integration tests into 5 collections (Authentication, User Management, Tenant Management, Authorization, Project & Settings) with trait-based filtering
• Updated CI workflow to run tests in parallel using a matrix strategy across separate jobs
• Enabled controlled parallelization in XUnit configuration (up to 4 threads)
