feat: local dashboard, health-history, brain row, agentdb fold-in + real harvest

[pacphi]

Ships four operator-facing capabilities and folds agentdb in as a first-class managed subsystem — closing the gap with (and going past) the ruflo-aqe-kit comparison. Everything new is read-only or opt-in; the learning-write path is proven live against real CLIs with no mocks.

What's in it

🖥️ ak x dashboard — local web dashboard

• Zero-dep node:http, 127.0.0.1 only, never detaches. Self-contained page (all CSS/JS inline, no external fetches) + GET /api/status reusing ak status --json via shell-out.
• "Refined technical instrument" design: serif+mono, theme-aware (dark/light with an icon toggle persisted to localStorage), grouped one-card-per-subsystem with severity triage (attention-first, healthy recessed), SVG sparklines, XSS-escaped.

📈 health-history ring

• Pure append/detectRegression over a kit.json ring; sync appends a post-heal snapshot; status flags backslides (learning shrank, native slots dropped, drift/security regressed).

🧿 statusline brain row

• Honesty-gated RuvNet-Brain segment (KB presence/size) in the activation footer.

🧩 agentdb — folded in as a managed subsystem

• Presence/version + coherence guard: the global agentdb CLI is pinned to ruflo's bundled agentdb so the shared cognitive store never skews on the core version (the FsyncFailed/brain.rvf corruption class). Wired into config (agentdb:true), setup (install), sync (repin), status + dashboard (live row).

🌱 ak x harvest — opt-in learning-write, no mocks

• Drives only grounded, present CLIs (ruflo hooks post-task, agentdb skill consolidate), parses their real output into structured evidence (skills created/updated, avg reward), skips honestly when agentdb is absent.
• Default-safe: off unless harvest:true; --dry-run writes nothing.
• ak x verify harvest: live end-to-end proof — seeds real episodes, consolidates a real skill, reads it back. Unit tests assert the parser against real captured output (no fake runner).

Verification

• pnpm typecheck 0 · pnpm lint 0 · 94 unit checks across 6 files pass
• ak x verify harvest green on real CLIs: seeded 3 episodes → created 1 skill (avg reward 0.9) → searchable

Notes for the reviewer

• Single commit: the shared seam files (bin/config/status/sync/setup/heal) interleave hunks from multiple features, so a file-based split would leave intermediate commits broken.
• Installs agentdb globally on first setup/sync (reversible: npm un -g agentdb).
• verify all (which now includes harvest) wasn't re-run in full this session (the other suites spawn slow ruflo/aqe trains); the harvest suite was verified in isolation.
