feat: add runtime harness for browser and Electron environments

- Updated package.json to include new test scripts for browser and Electron.
- Added Playwright configuration for running browser tests.
- Created a new HTML page for the CORTEX Runtime Harness to display runtime capabilities.
- Implemented Electron main process to launch the harness in an Electron window.
- Added scripts to run Electron runtime tests and a server for serving the harness.
- Developed Playwright tests for both browser and Electron harnesses to validate runtime capability reports.

 4. Keep Chromium as the web-parity lane; use Electron as the primary GPU/runtime realism lane.
 5. Serve the harness over `http://127.0.0.1` / `http://localhost` during development and testing; do not rely on `file://` for WebGPU-sensitive execution.
 
-## Next Session Highest Priority (P0)
+## Current Pass Highest Priority (P0)
 
-Stand up the browser-first runtime harness and thin Electron wrapper so real GPU/browser validation can begin, then connect adaptive embedding selection into that runtime path.
+Move from harness scaffolding to production validation by enabling Electron gate provisioning, wiring real providers, and implementing first ingest/query orchestration slices.
 
 Instruction:
-1. Create a minimal harness renderer that reports:
-   - `navigator.gpu` availability
-   - adapter/device acquisition outcome
-   - IndexedDB + OPFS availability
-   - selected embedding backend/provider kind
-2. Add a thin Electron main-process wrapper that:
-   - loads the same harness via localhost
-   - appends required Chromium switches before `ready`
-   - logs GPU feature status and GPU info after `gpu-info-update`
-3. Add Playwright coverage for two lanes:
-   - Chromium web harness
-   - Electron harness
-4. After the harness exists, register the first real embedding providers in `ProviderResolver` and test selection inside the real runtime lane.
-5. Keep strict TDD (Red -> Green -> Refactor).
-6. If a blocker appears, record it in this document under an error log entry and continue with the next actionable slice.
+1. Keep canonical docs synchronized (`README.md`, `CORTEX-DESIGN-PLAN-TODO.md`, `PROJECT-EXECUTION-PLAN.md`) before and after implementation slices.
+2. Provision Electron in CI/runtime images and remove local soft-skip in gated contexts.
+3. Register the first real embedding providers in `ProviderResolver` and test selection inside runtime lanes.
+4. Implement first `Hippocampus` ingest orchestration entry point with profile-resolved settings.
+5. Implement first `Cortex` retrieval orchestration entry point with deterministic coherence ordering baseline.
+6. Keep strict TDD (Red -> Green -> Refactor).
+7. If a blocker appears, record it in this document under an error log entry and continue with the next actionable slice.
 
 Definition of done for this pass:
-1. A single renderer harness runs under both Chromium and Electron.
-2. Electron lane emits GPU capability diagnostics on Linux.
-3. At least one real provider candidate is wired into resolver selection from the runtime harness.
+1. Canonical docs expose the same P0 priorities and maintenance protocol.
+2. Runtime browser lane passes from Playwright against shared harness.
+3. Electron lane has explicit provisioning contract and blocker handling.
 4. Any unresolved blocker is documented with file/symptom/next action.
