fix: Add default value to _print function parameter

[xerrors]

Summary

• Fix _print function to have a default empty string value for msg parameter
• This resolves an issue where calling _print() without arguments would fail at runtime

Problem

The _print function in web_launcher.py required a msg parameter with no default value:

sirchmunk/src/sirchmunk/cli/web_launcher.py

Lines 43 to 45 in d7a7ec9

	def _print(msg: str):
	"""Print with flush for real-time output."""
	print(msg, flush=True)

But it was being called without arguments in some code paths, causing the application to crash on startup.

sirchmunk/src/sirchmunk/cli/web_launcher.py

Lines 605 to 614 in d7a7ec9

	_print()
	_print("=" * 60)
	_print("✅ Development servers running!")
	_print("=" * 60)
	_print(f" Frontend: http://localhost:{frontend_port}")
	_print(f" Backend: http://localhost:{backend_port}")
	_print(f" API Docs: http://localhost:{backend_port}/docs")
	_print("=" * 60)
	_print()
	_print("Press Ctrl+C to stop all services.")

Solution

Added default empty string to the parameter:

def _print(msg: str = ""):  # Now has default value

Test plan

• Verified the script launches without errors
• _print() can now be called without arguments

Code Review

This pull request updates the _print utility function in web_launcher.py to allow calling it without arguments by setting a default value for the msg parameter. Feedback suggests adding an explicit -> None return type hint to the function signature to improve type safety and maintain consistency with the rest of the codebase.
