Extend GET /api/stats with per-shard memory health (counts, newest/oldest ages, same-tag duplication proxy, file/registration mismatch), an active user-profile summary, and a 14-day activity series parsed from the plugin's structured logs (captures, skips, profile/compaction injections, errors bucketed by message). Add a Stats tab rendering it, with per-section degradation so the view keeps reporting during database incidents. Read-only: no new writes or capture/injection behavior changes.
The stats aggregation test creates two shards, inserts three vectors, and runs the full handleStats walk in one it(). On the windows-latest runner that exceeds bun's default 5s per-test timeout; the timeout runs afterEach cleanup while the walk is still in flight, so per-shard reads fail against the deleted temp dir and the orphaned assertions report total 0. Give the test the same 30s budget plugin-bundle-boundary uses.

cool feature |
Keep ownership probes cheap with ?probe=1, commit shard totals only after a full walk succeeds, hard-fail shard listing for explorer totals, and align the sim fixture total with memories.json.

Summary
Adds a read-only health/stats view to the web UI so memory-system health is visible day-to-day instead of requiring manual log/DB audits.
GET /api/stats(existingtotal/byScope/byTypeunchanged) with:Turso ready gate failed,listMemories)opencode-mem.log.old, multi-day live files) are handled/stats(sidebar entry, routing, translations for en/de/zh/ar/tr/nl) rendering overview cards, the 14-day activity table with expandable error buckets, and a shard diagnostics table with mismatch/missing-file warningsOPENCODE_MEM_SIM=1 bun run web:dev) now serves a representative stats fixture so the tab is developable without a live storeNo new writes anywhere; capture/injection behavior untouched.

Known limitations: the same-tag count is a deliberately weak duplication proxy (a real near-duplicate rate needs an embedding similarity pass); log-based counters only cover days whose rotated log files still exist (rotation retains 30 days).
