Add WorkBuddy desktop setup recipe and 2026-09-12 thinking deviations

[JJasonSun]

Summary

Add a WorkBuddy desktop setup recipe with separate ordinary-text and thinking routes, plus dated ECNU response observations. The configuration follows current model capabilities; desktop implementation details retain their September inspection date.

WorkBuddy models.json
  ecnu-max      → ordinary text
  ecnu-reasoner → thinking, low / high / max
  both         → text-only, conservative context budget

Evidence

• Before: The Skill had no WorkBuddy recipe or references to these desktop/API observations. After: The recipe documents the array-shaped configuration, startup/editor behavior, request controls, and response checks, with current contracts separated from historical results.
• All 76 offline tests, repository validation, compilation, skills-ref validation, and whitespace checks passed. The configuration JSON was parsed and checked for route settings and context budgets.
• Current WorkBuddy behavior and the revised configuration were not live-tested. Dated API observations do not establish current model quality or service availability.
