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

What
- Added documentation for setting up SQLite on macOS.
- Covered installation approaches:
  - Using Homebrew: `brew install sqlite`.
  - Manual download of `sqlite-tools` package from official SQLite site.
- Explained how to verify installation:
  - Run `sqlite3 --version` in Terminal.
- Detailed usage examples:
  - `sqlite3 mydb.db` → create or open a database file.
  - `.tables` → list tables.
  - `.schema` → show table schema.

Why
- Provides a clear, step-by-step setup guide for macOS users.
- Ensures developers can quickly configure SQLite for query testing and JDBC integration.
- Aligns setup documentation across platforms (Windows, macOS).

How to use
1. Install SQLite:
   - With Homebrew:
     ```bash
     brew update
     brew install sqlite
     ```
   - Or download `sqlite-tools-osx-x86-x.y.z.zip` and extract to `/usr/local/sqlite`.
2. Verify installation:
   ```bash
   sqlite3 --version

	3.	Start SQLite shell:

sqlite3 mydb.db

	•	.tables → list available tables.
	•	.schema → check schema.
	•	.exit → quit shell.

Real-life Applications
	•	Ideal for developers needing a lightweight SQL database on macOS.
	•	Used in backend APIs, CLI tools, or local persistence for apps.
	•	Commonly leveraged for testing SQL queries without requiring MySQL/PostgreSQL setup.
	•	Fits seamlessly with Java via SQLite JDBC driver.

Notes
	•	SQLite on macOS installs system-wide when using Homebrew.
	•	Databases are file-based (.db file), portable across systems.
	•	Use the latest JDBC driver (sqlite-jdbc-x.y.z.jar) for Java database connectivity.
