"""Operator proficiency tracker — counts successful WO completions per
(employee, role) pair and auto-promotes the employee once the role's
mastery threshold is crossed.

The promotion mechanic lets managers casually train workers on the job:
they assign someone a task they've never done, the worker finishes it
successfully, and after N successes the role is added to the employee's
Shop Roles automatically. The operator never has to fill in a form;
their growing skill set just unlocks itself.
