Resolves #10949
Related: #10945

Adds a Dockerized Memory Core integration spec that seeds a sentinel memory, verifies semantic and graph evidence, creates an atomic backup bundle, deliberately wipes the session plus Native Edge Graph node/edge evidence inside the disposable compose fixture, proves healthcheck remains green while the sentinel is gone, then restores the bundle and verifies both semantic search and graph edges return. The branch also fixes the graph JSONL importer so restored edges preserve SQLite schema-required `id`, `user_id`, `source`, `target`, and `type` columns.

Evidence: L4 (GitHub Actions Docker integration job executed the deployed compose fixture and passed on `56d36f0c1`) -> L4 required (#10949 deployed destructive backup/wipe/restore proof). No residuals.

## Deltas from ticket

No product-scope additions. The test uses existing backup/restore orchestration and existing healthcheck/readiness surfaces rather than adding a new daemon-internal wipe alarm, matching the #10854 constraint. AC4 is implemented as an integration readiness/durability assertion: process health is intentionally shown insufficient, then semantic query and graph evidence provide the detector.

The Docker CI runs exposed two implementation gaps that are now fixed on this branch: container-side eval snippets needed Neo bootstrap before importing backup scripts, and graph import needed to write the full `Edges` schema rather than only `source`, `target`, and `data`.

## Test Evidence

- `node --check test/playwright/integration/BackupRestoreWipe.integration.spec.mjs` passed.
- `node --check ai/mcp/server/memory-core/services/DatabaseService.mjs` passed.
- `node --check test/playwright/unit/ai/mcp/server/memory-core/services/DatabaseService.graphBackup.spec.mjs` passed.
- `npm run test-unit -- test/playwright/unit/ai/mcp/server/memory-core/services/DatabaseService.graphBackup.spec.mjs` passed: 1 passed.
- `npm run test-unit -- test/playwright/unit/ai/buildScripts/backup.spec.mjs test/playwright/unit/ai/buildScripts/restore.spec.mjs test/playwright/unit/ai/mcp/server/memory-core/services/DatabaseService.graphBackup.spec.mjs` passed: 19 passed.
- `git diff --check origin/dev...HEAD` passed.
- Local `npm run test-integration -- test/playwright/integration/BackupRestoreWipe.integration.spec.mjs` exited 0 with 1 skipped because this environment has no Docker binary.
- GitHub Actions on `56d36f0c1`: CodeQL success, unit success, integration success, Analyze (javascript) success.

## Post-Merge Validation

None required for #10949. The Docker integration proof passed before ready-for-review handoff.

> **Challenge OR documented search (per guide §7.1):**
> 
> - **Challenge**: AC4 requires "Wipe/collapse is detected as a readiness/durability failure, not masked by process health." In the test, we execute `expect(wipedHealth.status).toBe('healthy')` and `expect(wipedHealth.database.connection.connected).toBe(true)`. This proves that process health *does* mask the collapse. The integration test queries the memory/graph to actually detect the wipe. Is the intention of AC4 satisfied simply by the integration test *acting* as the detector, or should the health endpoint itself reflect the failure? If the healthcheck *should* fail, then expecting `'healthy'` is testing the wrong state.

[AUTHOR_RESPONSE]

Gemini challenge on AC4 is accepted as a useful semantic clarification, but I do not think it requires changing the health endpoint in this PR.

My interpretation of #10949 AC4 is based on the ticket ledger row: `Integration assertion fails on wiped state before restore`. The test therefore intentionally proves two separate facts:

1. Process health is insufficient: after the wipe, `healthcheck.status === healthy` and the database connection is still connected.
2. Durability/readiness evidence fails: the sentinel semantic query is absent and the seeded graph node is absent before restore.

That means the detector in this PR is the deployed integration readiness assertion, not the existing liveness health endpoint. Making `healthcheck` itself emit a wipe alarm would re-enter the daemon-side primitive from #10854, which is closed as `not_planned`; that is why I kept this PR on the integration-proof lane and updated the PR body to say this explicitly.

I also fixed the CI failure from commit `2ffed0fe0`: container-side eval snippets now bootstrap `src/Neo.mjs` plus `src/core/_export.mjs` before importing backup/restore orchestration or Memory Core services. New head is `38f511c47`; CI rerun is pending.

[AUTHOR_UPDATE]

PR #10985 is now ready for human handoff.

Final head: `56d36f0c1`

CI on this head is green:
- CodeQL: success
- unit: success
- integration: success
- Analyze (javascript): success

The Docker integration job now provides the L4 evidence for #10949. I updated the PR body from residual/draft framing to `Evidence: L4 ... No residuals.`
