Update README.md Quick Start to reflect actual usage

[moshesham]

Problem

The README.md Quick Start guide shows commands that don't work:

# From README
python SQl_answer.py sql_basic_select

But SQl_answer.py doesn't accept command-line arguments in its current implementation.

Impact

• New users cannot follow quick start guide
• Poor first-time user experience
• Misleading documentation
• Frustration for contributors

Tasks

• Decide on updating README or adding CLI support
• Update README.md Quick Start section
• Test all commands in README
• Add troubleshooting section if needed
• Add example output for each command
• Update Docker usage examples if needed
• Ensure prerequisites are accurate

Additional README Improvements

• Add actual repository URL (currently shows placeholder)
• Add screenshots or example output
• Add FAQ section
• Add troubleshooting guide
