Subject: [PATCH] fix(agents): pass categories and skills to Sisyphus/Atlas
 prompts

Sisyphus and Atlas prompts were missing delegation guide because
availableCategories and availableSkills were not being passed to
createSisyphusAgent() and createAtlasAgent() in utils.ts.

This caused buildCategorySkillsDelegationGuide() to return empty string,
resulting in agents not knowing when/how to delegate to explore, librarian,
or use category+skills based delegation.
