fix: #2219 #2221 #2222 #2215 #2226 — memory/routing/statusline bug cluster (3.10.6) (#2227)

* fix: #2219 #2221 #2222 #2215 #2226 — memory/routing/statusline bug cluster (3.10.6) Five reproducible bugs reported by external contributors (pacphi, casparml, HF-teamdev), each verified against source and covered by a regression test. #2219 (silent write loss, Node 24/26) — agentdb pins better-sqlite3 as an OPTIONAL dep at ^11.8.1, which has no Node 24/25/26 prebuild; the native build fails silently and AgentDB drops to a non-persistent backend. Override better-sqlite3 to >=12.8.0 (ships Node 20–26 prebuilds) in BOTH the root umbrella and the ruflo wrapper (#2112: root overrides don't reach the wrapper). New CI guard audit-better-sqlite3-override.mjs prevents regression. #2226 (pattern store/search backend mismatch) — agentdb_pattern-store and agentdb_pattern-search hit disjoint backends, so stored patterns were never found. Two paths fixed: (a) when the ReasoningBank controller is present, bridgeSearchPatterns now reads LocalReasoningBank.findSimilar/getAll (the same backend store writes to); (b) when the controller is absent (the common real-world state), the memory-store-fallback search Tier-2 now hydrates entry content via getEntry — listEntries returns metadata only (see #2014), so the substring scan previously matched nothing. #2222 (route feedback no-op) — `route feedback` applied the Q-update in memory but the CLI exits before the Q-learner's autoSaveInterval fires, so learning never persisted. Add an explicit awaited router.saveModel() after feedback. #2221 (statusline shows V3.6 on global installs) — getPkgVersion() never probed the global npm root, so `npm i -g ruflo` fell back to the hard-coded default. Derive the global node_modules dir from process.execPath (no npm spawn) and probe it; covers nvm/mise and Windows layouts. Regenerated statusline.cjs. #2215 (flashAttention contradictory state) — system_info emitted a hard-coded `flashAttention: false` while hooks_intelligence reported the live probe. system_info now runs the same getFlashAttention() probe as the authoritative path so the two tools can't disagree. Tests: __tests__/bug-cluster-2219-2226.test.ts (5/5), statusline drift guard still byte-identical (8/8), tsc clean, targeted sweep 120/120. Co-Authored-By: RuFlo <ruv@ruv.net> * fix(deps): #2219 — sync package-lock to better-sqlite3@12.10.0 override npm ci validates lockfile against package.json; the override bumped the resolved version but the committed lockfile still pinned 11.10.0, failing 'npm ci' in CI. Regenerated with --package-lock-only. Co-Authored-By: RuFlo <ruv@ruv.net>

+/**
+ * Static guard for ruvnet/ruflo#2219 — keep the `better-sqlite3` override
+ * pinned to a version that ships Node 24/25/26 prebuilds.
+ *
+ * Why: `agentdb` declares `better-sqlite3` as an OPTIONAL dependency at
+ * `^11.8.1`. better-sqlite3 11.8.1 has no prebuilt binary for Node 24/25/26,
+ * so on those runtimes the optional native build fails *silently* (optional
+ * deps never error) and AgentDB falls back to a non-persistent backend —
+ * users on Node 24/26 saw stores succeed but never persist (silent write
+ * loss). better-sqlite3 >=12.8.0 ships prebuilds for Node 20–26.
+ *
+ * Per the #2112 lesson, root overrides do NOT propagate to the published
+ * `ruflo` wrapper — the override MUST be present in BOTH the root umbrella
+ * (`package.json`) and the wrapper (`ruflo/package.json`). This guard asserts
+ * both carry `better-sqlite3 >= 12.8.0`. Wired into v3-ci.yml.
+ *
+ * Exit codes:
+ *   0 — both overrides present and satisfy >=12.8.0
+ *   1 — missing override, or a range that admits a Node-24/26-broken version
