feat(assistant): one-time disclaimer note + GA4 question-report guide

- Add a subtle disclaimer under the greeting (EN/MK/SI): "automated guide,
  can make mistakes — check the linked page for official steps." Shown once,
  not on every message, so it sets expectations without clutter. Persistent
  footer disclaimer stays.
- docs/GA4-ASSISTANT-REPORT.md: step-by-step for registering the custom
  dimensions and building the "top questions" + "unanswered questions"
  explorations in GA4 (dev-only doc, not deployed).

+# Reading "Ask MSOS" questions in Google Analytics
+
+The assistant sends one Google Analytics event every time someone asks a
+question (only if they accepted cookies). This guide shows how to see those
+questions — your **real FAQs** and, most valuably, the questions it **couldn't
+answer** (so you know what to add next).
+
+Property: **G-WVYV807VSS**. You need *Editor/Admin* access to that GA4 property.
+
+---
+
+## What gets sent
+
+| Event name | `assistant_query` |
+|---|---|
+| `q` | the question text (first 120 chars) |
+| `result` | `curated` (great answer) · `search` (found pages) · `none` (**no answer — a gap!**) |
+| `q_lang` | language of the question: `en` / `mk` / `si` |
+| `page_lang` | language of the page they were on |
+
+---
+
+## Step 1 — Register the parameters (one-time, required)
+
+GA4 hides custom parameters until you register them as **custom dimensions**.
+Do this once:
+
+1. GA4 → **Admin** (gear, bottom-left) → **Custom definitions** → **Create custom dimension**.
+2. Create **four** dimensions, all with **Scope = Event**:
+   | Dimension name | Event parameter |
+   |---|---|
+   | Question | `q` |
+   | Result | `result` |
+   | Question language | `q_lang` |
+   | Page language | `page_lang` |
+3. Click **Save** for each.
+
+> ⚠️ Data only starts collecting into these dimensions **from the moment you
+> create them** (it isn't retroactive), so set them up early. Reports take
+> **24–48 h** to populate — but you can verify instantly in Step 2.
+
+---
+
+## Step 2 — Verify it's working right now (Realtime)
+
+1. Open the live site, **Accept** the cookie banner, open **Ask MSOS**, ask a test question.
+2. In GA4 → **Reports** → **Realtime**.
+3. Scroll to **"Event count by Event name"** → you should see **`assistant_query`**.
+   Click it to see the parameters coming in.
+
+(If you don't see it: make sure you clicked *Accept* on cookies — the event is
+intentionally not sent otherwise.)
+
+---
+
+## Step 3 — Build the "Top questions" report (Exploration)
+
+1. GA4 → **Explore** (left menu) → **Blank** exploration.
+2. **Variables** column → next to **Dimensions** click **+** → add **Question**,
+   **Result**, **Question language**. → next to **Metrics** click **+** → add **Event count**.
+3. In the **Settings** ("Tab Settings") column:
+   - **Rows** → drag in **Question**.
+   - **Values** → drag in **Event count**.
+   - **Filters** → drag in the field, choose... actually add a filter:
+     **Event name** `exactly matches` `assistant_query`.
+     (If "Event name" isn't offered, add the dimension **Event name** first.)
+4. You now have a ranked list of the most-asked questions. Sort by Event count (click the column).
+
+---
+
+## Step 4 — The gold mine: unanswered questions
+
+Duplicate the tab (or add a filter) and set:
+
+- **Rows**: Question
+- **Values**: Event count
+- **Filter**: **Result** `exactly matches` `none`
+
+This is the list of questions the assistant **failed to answer**. Each one is a
+prompt to either (a) add a curated answer in `assistant.js`, or (b) write/clarify
+a page. This is how the assistant gets smarter over time.
+
+Tip: also break down by **Question language** to see if MK/SI users are being
+served as well as EN users.
+
+---
+
+## Optional — a quick recurring check
+
+Save the exploration (it autosaves). Once a week, open it and look at:
+- **Top 10 questions** → your real FAQ list (consider promoting these on pages).
+- **`result = none`** → your to-do list for new answers/content.
+- **`result = search`** (not `curated`) → common questions worth turning into a
+  polished curated answer (edit the `INTENTS` list in `assistant.js`).
+
+---
+
+## Privacy note
+
+The question text is user-typed, so **avoid encouraging personal data** in the
+prompt (the placeholder just says "Ask a question…"). Google's terms forbid
+sending personal identifiers (emails, names) to GA. Questions are truncated to
+120 characters and only sent **after cookie consent**. If you ever want zero
+text stored, you can drop the `q` parameter in `assistant.js` and keep only the
+`result`/language counts.
