refactor: improve code structure and add better logging

- Replace custom logger with @atums/echo library
- Restructure imports using # path aliases
- Add request performance tracking and better request logging
- Improve type definitions and error handling
- Add custom file serving capability
- Update biome configuration with stricter linting rules
- Add comprehensive API documentation (DOCS.md)

+```
+
+### 5. API Info
+Get basic API information.
+
+```http
+GET /
+```
+
+**Example:**
+```bash
+curl "http://localhost:6600/"
+```
+
+## Response Format
+
+### Success Response
+```json
+{
+  "success": true,
+  "code": 200,
+  "posts": [
+    {
+      "id": 123456,
+      "file_url": "https://example.com/image.jpg",
+      "post_url": "https://example.com/post/123456",
+      "tags": "tag1 tag2 tag3",
+      "directory": 1234,

+
+### Error Response
+```json
+{
+  "success": false,
+  "code": 400,
+  "error": "Missing booru parameter"
+}
+```
+
+## Error Codes
+
+| Code | Description |
+|------|-------------|
+| 400 | Bad Request - Missing or invalid parameters |
+| 401 | Unauthorized - Missing authentication headers |
+| 403 | Forbidden - Booru is disabled |
+| 404 | Not Found - No results found or booru not found |
+| 405 | Method Not Allowed - Wrong HTTP method |
+| 406 | Not Acceptable - Wrong content type |
+| 500 | Internal Server Error |
+| 501 | Not Implemented - Feature not supported |
+
+## Usage Examples
+
+### Search for anime posts on Safebooru
+```bash
+curl -X POST "http://localhost:6600/safebooru/search" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "tags": ["anime", "girl"],
+    "results": 10,
+    "page": 0
+  }'
+```
+
+### Get random posts from Rule34
+```bash
+curl -X POST "http://localhost:6600/rule34/random" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "tags": ["pokemon"],
+    "excludeTags": ["gore"],
+    "results": 5
+  }'
+```
+
+### Search E621 with authentication
+```bash
+curl -X POST "http://localhost:6600/e621/search" \
+  -H "Content-Type: application/json" \
+  -H "e621UserAgent: MyApp/1.0 (by myusername on e621)" \
+  -H "e621Username: myusername" \
+  -H "e621ApiKey: myapikey" \
+  -d '{
+    "tags": ["canine"],
+    "results": 5
+  }'
+```
+
+### Get tag suggestions
+```bash
+curl "http://localhost:6600/gelbooru/autocomplete/anim" \
+  -H "gelbooruApiKey: your-api-key" \
+  -H "gelbooruUserId: your-user-id"
+```
+
+## Rate Limiting
+
+This API respects the rate limits of the underlying booru services. Please be mindful of your request frequency to avoid being blocked by the source APIs.
+
+## Notes
+
+- All POST requests require `Content-Type: application/json` header
+- Some boorus may have different response formats
+- E621 requires authentication for all requests
+- Gelbooru requires authentication for better rate limits
+- Tag formats may vary between boorus
+- The `tag_format` parameter allows you to choose between formatted strings or raw objects
