feat: CMS improvements batch 1-4

Batch 1:
- Fix .mcp.json formatting
- Remove type assertions in migration files
- Add aria-label to toast close button

Batch 2:
- Fix AddMemberModal accessibility (focus trap, Esc handler, aria)
- Add alt text to image-upload preview

Batch 3:
- Fix HeroSection color scheme (orange → green for brand consistency)

Batch 4:
- Replace getStats with COUNT queries for performance
- Image upload: progressive compression (quality 0.9→0.3, dimension 1920→720), never rejects
- Add meta info display (cover image, slug) to Article/Project/Member editors
- Document image upload pipeline in docs/knowledges/image-upload.md

 - Never use `as` or `any`. Let TypeScript infer types properly.
 - Never just "fire and forget". it crashes the entire server. instead, catch `.catch(console.error)` then forget, if you want to dispatch the job.
+- **NEVER use `$derived(await ...)` in Svelte 5.** This causes infinite loops and memory leaks. Use top-level `await` instead:
+  ```ts
+  // ❌ WRONG - causes memory leak
+  const data = $derived(await fetchData());
+
+  // ✅ CORRECT - use top-level await
+  const data = await fetchData();
+
+  // ✅ For reactive dependencies, use $derived without await
+  const filtered = $derived(data.filter(x => x.active));
+  ```

+## Size Limits
+
+```
+Browser (any size) → Compress → Server (10MB) → S3 (no limit)
+```
+
+| Stage | Limit | Enforcement |
+|-------|-------|-------------|
+| Browser input | None | User can upload any size |
+| Browser → Server | 10MB | Client compresses until it fits |
+| Server validation | 10MB (base64 ~13.7MB) | DoS protection |
+| Server → S3 | None | MinIO accepts any size |
+
+## Browser Compression
+
+Located in `$lib/shared/logic/image-processing.ts`:
+
+```ts
+const SERVER_LIMIT = 10 * 1024 * 1024; // 10MB
+const QUALITY_STEPS = [0.9, 0.7, 0.5, 0.3];
+const DIMENSION_STEPS = [1920, 1440, 1080, 720];
+```
+
+Algorithm:
+1. Start at 1920px, quality 0.9
+2. If > 10MB, reduce quality (0.9 → 0.7 → 0.5 → 0.3)
+3. If all qualities fail, reduce dimension (1920 → 1440)
+4. Reset quality, repeat
+5. Max 16 attempts (4 qualities × 4 dimensions)
+6. Best-effort: if still > 10MB after all attempts, return smallest achieved
+
+## Server Validation
+
+Located in `$lib/data/private/storage.remote.ts`:
+
+```ts
+const MAX_BASE64_SIZE = Math.ceil(10 * 1024 * 1024 * 1.37);
+```
+
+- Base64 adds ~37% overhead
+- 10MB file → ~13.7MB base64
+
+## Design Decisions
+
+- **Never reject user uploads**: Compress instead of refusing
+- **Quality over size**: Try high quality first, only reduce if needed
+- **GIF exception**: GIFs skip compression (animation would be lost)

 6. **Security**: Never read `.env` files, use `.env.sample` or `.env.example`
 7. **Type Safety**: Never use `as` or `any`, let TypeScript infer
 8. **Error Handling**: Never "fire and forget", use `.catch(console.error)` for async jobs
+9. **Remote Functions**: Always use explicit arrow functions with `query()` and `command()`
