feat: AI Agents sidebar section (setup + playground)

Promotes the AI assistant out of Settings into a first-class "AI Agents"
sidebar area.

- Sidebar: new "AI Agents" item → /agents.
- /agents page with two tabs:
  - Playground — a test chat (POST /api/ai/playground) that runs the
    real auto-reply path (KB retrieval + provider, auto_reply prompt,
    multi-turn, shows handoff). loadAiConfig gains requireActive so you
    can test before enabling.
  - Setup — the existing provider/key + knowledge-base config, relocated.
- Removed the AI section from Settings (settings-sections + page); same
  account config, new home. No migration.

Tests +6 (query, loadAiConfig requireActive). 593 pass; typecheck, lint,
build green.

+## [0.7.0] — 2026-07-02
+
+Promotes the AI assistant to a first-class **AI Agents** section in the
+sidebar — it's no longer tucked inside Settings.
+
+### Added
+
+- **AI Agents (sidebar).** A dedicated `/agents` area with two tabs:
+  - **Playground** — a test chat to message your agent and see its
+    grounded, multi-turn replies (and where it would hand off to a human)
+    *before* it ever answers a real customer. Runs the exact same path as
+    the auto-reply bot (knowledge-base retrieval + your provider), and
+    works even before you flip the master switch on, so you can try, then
+    enable. Backed by `POST /api/ai/playground`.
+  - **Setup** — the provider/key, business context, knowledge base, and
+    auto-reply controls (moved here from Settings → AI Assistant).
+
+### Changed
+
+- The AI configuration moved out of **Settings → AI Assistant** into the
+  new **AI Agents** section. No data change — same account config, new
+  home. No migration required.

 ## [0.6.0] — 2026-07-02
