refactor(rules): restructure into common + language-specific directories

* refactor(rules): restructure rules into common + language-specific directories

- Split 8 flat rule files into common/, typescript/, python/, golang/
- common/ contains language-agnostic principles (no code examples)
- typescript/ extracts TS/JS specifics (Zod, Playwright, Prettier hooks, etc.)
- python/ adds Python rules (PEP 8, pytest, black/ruff, bandit)
- golang/ adds Go rules (gofmt, table-driven tests, gosec, functional options)
- Replace deprecated ultrathink with extended thinking documentation
- Add README.md with installation guide and new-language template

* Fix installation commands for rules

Updated installation instructions to copy all rules to a single directory.

* docs: update README.md to reflect new rules directory structure

+## API Response Format
+
+```typescript
+interface ApiResponse<T> {
+  success: boolean
+  data?: T
+  error?: string
+  meta?: {
+    total: number
+    page: number
+    limit: number
+  }
+}
+```
+
+## Custom Hooks Pattern
+
+```typescript
+export function useDebounce<T>(value: T, delay: number): T {
+  const [debouncedValue, setDebouncedValue] = useState<T>(value)
+
+  useEffect(() => {
+    const handler = setTimeout(() => setDebouncedValue(value), delay)
+    return () => clearTimeout(handler)
+  }, [value, delay])
+
+  return debouncedValue
+}
+```
+
+## Repository Pattern
+
+```typescript
+interface Repository<T> {
+  findAll(filters?: Filters): Promise<T[]>
+  findById(id: string): Promise<T | null>
+  create(data: CreateDto): Promise<T>
+  update(id: string, data: UpdateDto): Promise<T>
+  delete(id: string): Promise<void>
+}
+```
