Proposed Changes

• Changed LoadTemplates and LoadTemplatesWithTags to return ([]*templates.Template, error) instead of []*templates.Template
• Replaced panic() calls with proper error returns when dialers are missing or waitgroup creation fails
• Updated Load() function and all callers to handle the new error returns
• Updated benchmark tests to handle the new return values
