feat: Continue Python environment setup even without API keys

Modified run-server.sh to allow developers to set up the Python development
environment without having API keys configured. This enables:

- Developers to clone and immediately start working on the codebase
- Running tests that don't require API calls
- Browsing and understanding the code structure
- Adding API keys later when ready to test MCP server functionality

Changes:
- Added new check_api_keys() function that warns but doesn't exit
- Changed print_error to print_warning for missing keys
- Updated main() to use check_api_keys instead of validate_api_keys || exit 1
- Kept original validate_api_keys() for backward compatibility

The script now shows a warning when API keys are missing but continues
with the full Python environment setup, dependencies installation, and
Claude configuration.
