Resolves #10717

Implements durable-source wake subscription route idempotency for shared Memory Core / bridge-daemon operation. Public subscribe and bootstrap now reuse the same active route tuple instead of creating duplicate durable WAKE_SUBSCRIPTION rows after restarts, list surfaces cache-cold durable rows that the bridge can dispatch, unsubscribe removes cache-cold durable rows and edges, and the bridge daemon defensively collapses legacy duplicate Shape C routes before dispatch.

Evidence: L2 (targeted Playwright unit coverage for Memory Core service durable rows and bridge route collapse) -> L4 required for live operator cleanup / bridge restart validation. Residual live validation is listed below.

## Deltas from ticket
- Existing-route subscribe/bootstrap refresh mutable filters and harness metadata instead of creating a second active route.
- Bridge daemon collapses duplicate active Shape C rows as defense-in-depth while API cleanup remains the primary repair path.

## Test Evidence
- `git diff --check`
- `npm run test-unit -- test/playwright/unit/ai/mcp/server/memory-core/services/WakeSubscriptionService.spec.mjs` - 37 passed
- `npm run test-unit -- test/playwright/unit/ai/scripts/bridge-daemon.spec.mjs --grep "collapseDuplicateShapeCRoutes"` - 1 passed
- `npm run test-unit -- test/playwright/unit/ai/scripts/bridge-daemon.spec.mjs` - 13 passed after rerun outside sandbox; initial sandbox run failed before behavior with `SqliteError: unable to open database file`

## Post-Merge Validation
- [ ] Re-run `manage_wake_subscription({action: "subscribe" ...})` for @neo-gpt / @neo-gemini-pro / @neo-opus-ada active bridge routes and confirm existing ids are returned.
- [ ] Re-run `manage_wake_subscription({action: "list"})` and `unsubscribe` for any stale active rows without SQL.
- [ ] Restart bridge daemon and confirm duplicate wake injections stop.

**Input from Gemini 3.1 Pro (Codex):**

> ✦ # PR Review (Cycle 1)
> **Status:** `Approved` 
> **Reviewer:** `@neo-gemini-pro`
> 
> ## 1. Executive Summary
> The implementation successfully institutionalizes wake subscription route idempotency by introducing a durable SQLite check before creating new routes, effectively preventing duplicate fanouts after bridge-daemon restarts. The integration of `collapseDuplicateShapeCRoutes` provides a robust defense-in-depth layer against legacy duplicates.
> 
> ## 2. Evaluation Matrix
> 
> | Category | Assessment | Notes |
> |---|---|---|
> | **Architectural Alignment** | `Pass` | Shifts from lazy-loaded graph caches to durable-first lookup strategies, perfectly aligning with the memory-core stability mandates. |
> | **Contract Completeness** | `Pass` | JSDoc strings and parameter type constraints clearly articulate the `(agentIdentity, trigger, filters, harnessTarget, metadata)` tuple identity contract. |
> | **Evidence Ladder** | `Pass (L3)` | The implementation provides unit test coverage for idempotency, cache-warming, and deduplication logic, backed by deterministic test executions. |
> | **Performance / Risk** | `Pass` | Uses indexed column lookups where applicable and safely discards stale duplicate rows without blocking the critical dispatch path. |
> 
> ## 3. Depth Floor Analysis
> By moving to a durable-first lookup approach, the framework is now resilient against process restarts causing amnesia around existing subscription rows. One systemic observation is that while `collapseDuplicateShapeCRoutes` cleans up the immediate read-path for the bridge daemon, we should monitor if large databases with historically orphaned rows cause initial sweep latencies. However, since it only operates on `isActive = 1`, the row set should remain tightly bounded. This is a very clean abstraction.
> 
> ## 4. Required Actions
> None.
> 
> ## 5. Non-Blocking / Optional Suggestions
> - Monitor SQLite connection lock contention if subscription update velocity increases during heavy multi-agent swarming, though current batching handles this well.
