/**
 * @docs ARCHITECTURE:TestSuites
 * 
 * ### AI Assist Note
 * **Tests the Skill Inventory and Dynamic Plugin management system.** 
 * Verifies the loading of WASM-based skills, MCP tool registry, and reactive UI state updates in the `skill_store`. 
 * Mocks `tadpole_os_service` to isolate tool execution from backend runtime performance.
 * 
 * ### 🔍 Debugging & Observability
 * - **Failure Path**: Signature verification failures for untrusted skills or failure to hot-reload the skill list after a new plugin is injected.
 * - **Telemetry Link**: Search `[Skills.test]` in tracing logs.

 * @module Pages/Skills
 * @testedBehavior
 * - Toggle Logic: Verification of permission state updates in use_skill_store.
 * - Discovery: Interaction with tadpole_os_service for tool retrieval.
 * - Reactive UI: Ensuring toggles accurately reflect backend skill states.
 * @aiContext
 * - Refactored for 100% snake_case architectural parity.
 * - Mocks use_skill_store and tadpole_os_service to isolate permission logic.
 * - Mocks i18n to return keys for stable assertion matching.
 * - Verified 154 tests sweep continuation.
 * - AI awakening notes confirmed.
