v3.10.6

## Ruflo v3.10.6 — memory, routing & statusline bug-fix release

Five reproducible bugs reported by external contributors (**@pacphi**, **@casparml**, **@HF-teamdev**), each verified against source and covered by a regression test. Thanks to all three for the detailed, well-traced reports.

### 🔴 #2219 — Silent write loss on Node 24/26
`agentdb` declares `better-sqlite3` as an **optional** dependency at `^11.8.1`, which has no prebuilt binary for Node 24/25/26. On those runtimes the optional native build fails *silently* (optional deps never error), and AgentDB drops to a non-persistent backend — stores appear to succeed but never land on disk.

**Fix:** override `better-sqlite3` → `>=12.8.0` (ships Node 20–26 prebuilds) in **both** the root umbrella and the `ruflo` wrapper (root overrides don't propagate to the published wrapper — the #2112 lesson). A new CI guard (`audit-better-sqlite3-override.mjs`) keeps the override pinned so this can't regress.

> If you installed globally on Node 24/26 before this release: `npm i -g ruflo@latest` restores the native backend.

### 🔴 #2226 — `agentdb_pattern-store` / `agentdb_pattern-search` never agreed
The store and search MCP tools hit **disjoint backends**, so a stored pattern was never returned by search. Two paths fixed:
- **Controller present:** `bridgeSearchPatterns` now reads `LocalReasoningBank.findSimilar`/`getAll` — the same backend the store writes to.
- **Controller absent (the common case):** the `memory-store-fallback` search now hydrates each entry's content via `getEntry` before matching — `listEntries` returns metadata only (see #2014), so the substring scan previously matched nothing.

### 🟠 #2222 — `route feedback` was a no-op
Feedback applied the Q-learner update in memory, but the CLI process exits before the `autoSaveInterval` flush fires, so route-learning never persisted across invocations. **Fix:** explicit awaited `router.saveModel()` after feedback.

### 🟡 #2221 — Statusline showed `RuFlo V3.6` on global installs
`getPkgVersion()` never probed the global npm root, so `npm i -g ruflo` fell back to the hard-coded default version. **Fix:** derive the global `node_modules` dir from `process.execPath` (no npm spawn — statusline renders often); covers nvm/mise and Windows layouts.

### 🟡 #2215 — `flashAttention` reported contradictory state
`system_info` emitted a hard-coded `flashAttention: false` while `hooks_intelligence` reported the live probe. **Fix:** `system_info` now runs the same `getFlashAttention()` probe as the authoritative path, so the two tools can't disagree.

---

### Verification
- New regression suite `bug-cluster-2219-2226.test.ts` — 5/5 (incl. end-to-end store→search roundtrip)
- Statusline drift guard — 8/8 (regenerated `.cjs` byte-identical to generator)
- `tsc` clean; CI **29/29 green** including the new better-sqlite3 override guard

### Install
```bash
npm i -g ruflo@latest        # or @3.10.6
npx ruflo@latest --version   # → 3.10.6
```

All three packages (`@claude-flow/cli`, `claude-flow`, `ruflo`) published at 3.10.6 with `latest`/`alpha`/`v3alpha` in lockstep.
