Pull request overview

Updates specifications to reflect recent Platform API/environment changes and extends the Utils specification with a plugin system, adding integration test scaffolding (dummy plugin + tests) to validate plugin discovery/registration.

Changes:

• Update SPEC_PLATFORM_SERVICE to include the test environment and document ApplicationRun.results() filtering parameters.
• Extend SPEC-UTILS-SERVICE + add new requirements/features around plugin discovery and CLI/GUI registration.
• Add integration tests + a dummy plugin package used to verify plugin auto-discovery (and update pre-commit exclusion for test resources).
