fix(skill): name sendmark's workers by class, not a partial mode list

sendmark's comment and verbs.md 5.5 listed six external modes by name,
and test/agent-skill-mode-lists.test.ts refuses any partial list of them
(the one a ninth CLI would silently miss). Both now say what the class
is: a hook-less claude, a worker on the local model, and every external
agent mode but deepseek.
