Reduce Redundant Error-Level Logging #421

Is your feature request related to a problem?

The codebase uses logger.error in places where the situation isn't an actual error — for example, when a resource is simply not found.
This creates log noise and makes it harder to identify genuine errors.

if not credentials:
logger.error(f"No credentials found for project {project_id}")

Describe the solution you'd like

Define clear guidelines for log levels:
- error: Unexpected exceptions, failures, or situations where the system cannot proceed
- warning: Recoverable conditions, user-caused validation errors
- info: Expected conditions that are worth noting
- No log: Entirely expected behavior (e.g., resource legitimately doesn't exist)

Action items:

• Review all logger.error usages across the codebase
• Downgrade to warning, info, or remove based on context
• Document logging conventions for future development
