Resolves #10917

PR #10926 completed Phase 1 and exposed the real failure payload: `Tool Error: Failed to add memory. Message: connect ECONNREFUSED 127.0.0.1:11434`. This PR fixes that root cause by adding a deterministic OpenAI-compatible embedding endpoint to the integration compose stack, wiring Memory Core to it, removing the CrossTenantIsolation CI skip, and keeping richer MCP tool-error assertion output for future failures.

Evidence: L3 achieved (GitHub Dockerized integration CI passed with CrossTenantIsolation unskipped) -> L3 required. No residuals.

## Deltas from ticket
- Phase 1 diagnostic PR #10926 was closed after extracting the payload.
- Phase 2 fix keeps the real `openAiCompatible` HTTP embedding path instead of adding a runtime test-only provider.

## Test Evidence
- `git diff --cached --check`
- `git diff --check origin/dev...HEAD`
- `node --check ai/deploy/mock-openai-embedding-server.mjs`
- `node --check test/playwright/integration/fixtures/mcpClient.mjs`
- `node --check test/playwright/integration/CrossTenantIsolation.integration.spec.mjs`
- `node --input-type=module -e "import fs from 'node:fs'; import yaml from 'js-yaml'; yaml.load(fs.readFileSync('ai/deploy/docker-compose.test.yml', 'utf8')); console.log('yaml ok');"`
- Local mock endpoint smoke: `200 2 4096 1` for `/v1/embeddings` on port 19134.
- `npm run test-integration -- test/playwright/integration/CrossTenantIsolation.integration.spec.mjs` -> `1 skipped` locally because Docker is unavailable in Codex.
- PR #10927 CI: `integration` passed in 1m59s, `Analyze (javascript)` passed, CodeQL passed.

## Post-Merge Validation
- [ ] Confirm #10917 auto-closes after squash merge.

> ✦ # PR Review Summary
> 
> **Status:** Approve
> 
> ### 🪜 Strategic-Fit Decision
> 
> Per §9 Strategic-Fit Step-Back:
> - **Decision**: Approve
> - **Rationale**: The PR cleanly solves the root cause identified in the Phase 1 diagnostic. By provisioning a deterministic mock embedding server directly in the compose stack, it restores test hermeticity without requiring external ollama dependencies. The CI tests now pass cleanly and the #10917 skip is removed.
> 
> **Peer-Review Opening:** Thanks for putting this together! Great approach to provisioning the integration embeddings. The deterministic node endpoint successfully unblocked the Dockerized integration tests and closed the gap we found in Phase 1. I've left some review notes below. Let's get these squared away so we can merge.

> **Challenge OR documented search (per guide §7.1):**
> 
> - **Documented search**: I actively looked for potential race conditions with the new `embedding-server` service in the compose stack and found no concerns; it correctly includes a robust `healthcheck` and the `memory-core` service properly uses `depends_on: embedding-server: condition: service_healthy`. I also verified that any leftover `#10917` CI skips were successfully removed from `CrossTenantIsolation.integration.spec.mjs`.

> *   **`[KB_GAP]`**: none
> *   **`[TOOLING_GAP]`**: none
> *   **`[RETROSPECTIVE]`**: The strategy of using a tiny node-based mock server in `docker-compose.test.yml` to satisfy external LLM/Embedding dependencies is a clean, hermetic pattern that should be reused for future integration tests requiring mocked AI services.

> ### 📊 Evaluation Metrics
> *   **`[ARCH_ALIGNMENT]`**: 100 - I actively considered framework alignment and test paradigms and confirmed none apply since providing a deterministic mock endpoint in the test compose stack is the preferred architecture for hermetic integration tests.
> *   **`[CONTENT_COMPLETENESS]`**: 100 - I actively considered documentation gaps and confirmed none apply; the code comments thoroughly explain the purpose of the mock endpoint and the docker-compose setup.
> *   **`[EXECUTION_QUALITY]`**: 100 - I actively considered race conditions or syntax errors and found none; the mock server uses node builtins safely, the healthcheck is robust, and tests passed.
> *   **`[PRODUCTIVITY]`**: 100 - I actively considered the ticket goals and confirmed the solution effectively removed the CI skip by fixing the root cause.
> *   **`[IMPACT]`**: 40 - Fixes a significant test integration gap enabling end-to-end memory isolation tests to run in CI.
> *   **`[COMPLEXITY]`**: 30 - Low: Added a simple http server and updated the docker-compose YAML.
> *   **`[EFFORT_PROFILE]`**: Quick Win - High ROI/Low Complexity resolving a blocking CI issue.
