Subject: [PATCH 1/3] feat: add make verify infrastructure with expected
 outputs for all 12 examples

- Add scripts/normalize_output.sh for reproducible output comparison
- Add expected output files for 6 pycubrid and 6 SQLAlchemy examples
- Add verify and demo targets to Makefile (Python-only)
- Fix non-deterministic sort order in 04_relationships.py
- Simplify GETTING_STARTED.md to under 20 lines with 3-line quick start

Closes #8 (reimplemented from scratch after branch deletion)
Partial #7 (verify infrastructure + fundamentals expected outputs)

-# CUBRID in 5 Minutes — Getting Started Guide
-
-> Pick your language. Connect to CUBRID. Build something. All in 5 minutes.
-
-This guide gets you from zero to a working CUBRID application in your language of choice. No prior CUBRID experience needed.
-
-## Prerequisites
-
-```bash
-# Start a CUBRID database with Docker (one command)
-docker run -d --name cubrid -p 33000:33000 -e CUBRID_DB=testdb cubrid/cubrid:11.2
-```
-
-Wait ~10 seconds for startup, then choose your language below.
-
----
-
-## 🐍 Python
-
-### Option A: SQLAlchemy ORM (Recommended)
-
-```bash
-pip install sqlalchemy-cubrid[pycubrid]
-```
-
-```python
-from sqlalchemy import create_engine, String
-from sqlalchemy.orm import DeclarativeBase, Mapped, Session, mapped_column
-
-class Base(DeclarativeBase):
-    pass
-
-class User(Base):
-    __tablename__ = "users"
-    id: Mapped[int] = mapped_column(primary_key=True, autoincrement=True)
-    name: Mapped[str] = mapped_column(String(100))
-    email: Mapped[str] = mapped_column(String(200), unique=True)
-
-engine = create_engine("cubrid+pycubrid://dba@localhost:33000/testdb")
-Base.metadata.create_all(engine)
-
-with Session(engine) as session:
-    # Create
-    user = User(name="Alice", email="alice@example.com")
-    session.add(user)
-    session.commit()
-
-    # Read
-    users = session.query(User).all()
-    for u in users:
-        print(f"{u.name} ({u.email})")
-```
-
-### Option B: Direct Driver
-
-```bash
-pip install pycubrid
-```
-
-```python
-import pycubrid
-
-conn = pycubrid.connect(host="localhost", port=33000, database="testdb", user="dba")
-cursor = conn.cursor()
-
-cursor.execute("""
-    CREATE TABLE IF NOT EXISTS products (
-        id INT AUTO_INCREMENT PRIMARY KEY,
-        name VARCHAR(100) NOT NULL,
-        price DOUBLE
-    )
-""")
-
-cursor.execute("INSERT INTO products (name, price) VALUES (?, ?)", ("Widget", 9.99))
-conn.commit()
-
-cursor.execute("SELECT * FROM products")
-for row in cursor.fetchall():
-    print(row)
-
-cursor.close()
-conn.close()
-```

----
-
-## 🟦 TypeScript / Node.js
-
-### Option A: Drizzle ORM (Recommended)
-
-```bash
-npm install drizzle-cubrid drizzle-orm cubrid-client
-```
-
-```typescript
-import { createClient } from "cubrid-client";
-import { drizzle, cubridTable, varchar, integer, serial, sql } from "drizzle-cubrid";
-
-// Define schema
-const users = cubridTable("users", {
-  id: serial("id").primaryKey(),
-  name: varchar("name", { length: 100 }).notNull(),
-  email: varchar("email", { length: 200 }).unique(),
-});
-
-// Connect
-const client = createClient({
-  host: "localhost",
-  port: 33000,
-  database: "testdb",
-  user: "dba",
-});
-const db = drizzle(client);
-
-// Create table
-await db.execute(sql`CREATE TABLE IF NOT EXISTS users (
-  id INT AUTO_INCREMENT PRIMARY KEY,
-  name VARCHAR(100) NOT NULL,
-  email VARCHAR(200) UNIQUE
-)`);
-
-// Insert
-await db.insert(users).values({ name: "Alice", email: "alice@example.com" });
-
-// Query
-const allUsers = await db.select().from(users);
-console.log(allUsers);
-
-await client.close();
-```
-
-### Option B: Direct Client
-
-```bash
-npm install cubrid-client
-```
-
-```typescript
-import { createClient } from "cubrid-client";
-
-const db = createClient({
-  host: "localhost",
-  port: 33000,
-  database: "testdb",
-  user: "dba",
-});
-
-type User = { id: number; name: string; email: string };
-
-// Typed query results
-const users = await db.query<User>("SELECT * FROM users WHERE name = ?", ["Alice"]);
-console.log(users); // User[] with full type safety
-
-// Transactions with auto-rollback
-await db.transaction(async (tx) => {
-  await tx.query("INSERT INTO orders (item) VALUES (?)", ["Widget"]);
-  await tx.query("UPDATE inventory SET qty = qty - 1 WHERE item = ?", ["Widget"]);
-});
-
-await db.close();
-```

Subject: [PATCH 2/3] feat: extend make verify to migration, quickstart, and
 batch-etl examples

Add expected output files for 11 additional examples beyond the
initial 12 fundamentals, bringing total coverage to 23/23 runnable
examples passing make verify.

Fixes:
- migration/03_crud_orm.py: use :.2f in __repr__ for CUBRID float precision
- migration/05_batch_operations.py: reorder main block so UPDATE/DELETE
  operate on correct dataset instead of post-reset empty table
- quickstart/5min-sqlalchemy/app.py: add drop_all before create_all for
  deterministic auto_increment IDs
- templates/batch-etl/seed_data.py: rename to 00_seed_data.py for correct
  sort-order execution in find|sort pipeline
- scripts/normalize_output.sh: add bare Version: pattern normalization

Subject: [PATCH 3/3] ci: update workflows for restructured Python-only layout

- ci.yml: remove Node/Go lint jobs, run ruff on repo root instead of
  obsolete python/ directory
- smoke-test.yml: replace old multi-language matrix with single
  make verify job against CUBRID service
- Format 4 Python files to pass ruff format --check
