Audit codebase to ensure all output uses the log utility

[ephur]

Find and replace any remaining print() or click.echo() calls with the appropriate log.level() variant. Consider static check or grep pattern for enforcement.

🤖 Initial triage (AI-generated):

This audit ensures all output goes through the log() system instead of raw print() or click.echo(). This will enforce consistency across formats and support structured logging (see #105, #107).

⚙️ Suggested approach:

• grep -Rn "print(" tfworker
• grep -Rn "click.echo" tfworker
• Migrate to log.msg() or log.<level>()

🧪 Optional: Add a pre-commit check or lint rule for enforcement.
