feat(sqlite-setup): add SQLite setup guide for Windows environment

What
- Added documentation for setting up SQLite on Windows OS.
- Covered key steps:
  - Downloading `sqlite-tools` from the official SQLite website.
  - Extracting the zip file to a dedicated folder (e.g., `C:\sqlite`).
  - Adding the folder path to Windows `PATH` environment variable.
  - Verifying installation by running `sqlite3` command in Command Prompt.
- Explained how to create/open a database:
  - `sqlite3 mydb.db` → creates or opens the database file.
  - `.tables` → view available tables.
  - `.schema` → view schema of tables.

Why
- Provides a clean setup guide for beginners working with SQLite on Windows.
- Ensures developers can quickly configure SQLite to run queries and connect via JDBC in Java.
- Standardizes environment setup across teams.

How to use
1. Download SQLite tools (sqlite-tools-win32-x86-x.y.z.zip).
2. Extract to `C:\sqlite`.
3. Add `C:\sqlite` to PATH:
   - Control Panel → System → Advanced system settings → Environment Variables.
   - Edit PATH variable → add new entry `C:\sqlite`.
4. Open Command Prompt:
   ```bash
   sqlite3

	•	Should open SQLite shell with sqlite> prompt.

Real-life Applications
	•	Lightweight database for prototyping or small apps.
	•	Backend storage for local desktop or embedded applications.
	•	Used in Android development for local data persistence.
	•	Handy for practicing SQL queries without heavy DBMS installation.

Notes
	•	SQLite is serverless and file-based; .db file contains the entire database.
	•	Use .exit or .quit to close the SQLite shell.
	•	Ensure correct JDBC driver (sqlite-jdbc-x.y.z.jar) when integrating with Java.
