v0.17.4

Added

• Added first-class learning no-op terminal outcomes for Analyst, Professor, and Curator so reviewed no-change learning requests close as done instead of appearing blocked.

Changed

• Changed built-in learning-mode generic Doublechecker success learning to start at Analyst instead of direct Curator, keeping vague success evidence in the research stage.

Fixed

• Compile validation now rejects direct Curator learning trigger rules unless they include target_skill_id or preferred_output_paths, preventing runtime-generated Curator requests that have no safe skill destination.
