Add core-to-SDK integration testing pipeline and matrix verification

This commit introduces:
- A unified verification script (scripts/verify-all.sh) to test all SDKs against a live core server.
- Comprehensive integration tests for Python (pytest) and TypeScript (jest/ts-jest).
- Automated server lifecycle management during testing using pmxt-ensure-server.
- Full assertions for data structure, type safety, and cross-exchange consistency.
- Testing documentation in TESTING.md.

+# PMXT Testing Strategy
+
+To ensure 100% certainty that all individual SDKs function correctly within the monorepo structure, we implement a **Unified Integration Test Pipeline**.
+
+## The Challenge
+
+In a monorepo with a shared backend (`core`) and multiple client SDKs (`sdks/python`, `sdks/typescript`), unit tests are insufficient. They only verify isolated logic. We need to verify the *communication* between the SDKs and the running Sidecar Server.
+
+## The Solution: Matrix Integration Testing
+
+We define a "Golden Path" of operations that every SDK must support (e.g., `Fetch Markets`, `Get Orderbook`). We then run these operations against a live local server.
+
+### Workflow
+
+1.  **Build Core**: Ensure the latest `core` server code is built.
+2.  **Start Sidecar**: Launch the `pmxt` server in the background.
+3.  **Run SDK Validation**:
+    *   **TypeScript**: execute `sdks/typescript/examples/market-data/get_event_prices.ts`
+    *   **Python**: execute `sdks/python/examples/market-data/get_event_prices.py`
+4.  **Verify**: If all scripts exit with code `0`, the SDKs are correctly communicating with the server.
+
+## How to Verify Locally
+
+We have created a script to automate this:
+
+```bash
+./scripts/verify-all.sh
+```
+
+## Continuous Integration (CI)
+
+This logic should be part of the CI pipeline (e.g., GitHub Actions). on every PR:
+1.  Checkout code.
+2.  Install dependencies.
+3.  Run `./scripts/verify-all.sh`.
