feat: add /summary, /setbreak, weekly totals, and fix command dispatch for arg-bearing commands

- Add /summary [YYYY-MM] command for monthly work/break/day-off totals

- Add weekly totals row to main menu status

- Add /setbreak <minutes> for configurable daily break threshold

- Fix HandleMessage routing: extract command name instead of exact match (fixes /export YYYY-MM, /edit, /note, /summary, /setbreak)

- Update README with full command table and configurable break docs
