Release v0.17.58

Improvements

Improved reliability for agents with large skill catalogs. Built-in capabilities — current time, long-term memory, posts, activities, and sub-agent calls — now remain available even when the automatic tool-selection layer narrows the active tool set. Previously these core tools could be filtered out, causing agents to repeatedly attempt the same failed call without recovering.
Raised the threshold at which the automatic tool-selection layer activates and refined the counting logic so built-in provider tools no longer push borderline agents into the selection path prematurely.
