Function handle_total 

pub fn handle_total(text: &str, entry: &mut Entry)

Handle thr:total text content

Parses non-negative integer from text. Silently ignores non-numeric, negative, overflow, empty, and whitespace-only values (consistent with how parse_duration handles invalid input throughout the codebase).

Arguments

• text - Text content of the thr:total element
• entry - Entry to update with the parsed count
