fix: update documentation to use load_skills instead of skills parameter (#1088)

All documentation, agent prompts, and skill descriptions were still
referencing the old 'skills' parameter name for delegate_task, but the
tool implementation requires 'load_skills' (renamed in commit aa2b052).
This caused confusion and errors for users following the docs.

Fixes #1008
