log-learning

Append a structured learning (bug, error, friction, surprise, or improvement idea) to the PUMPD "Agent Learnings" log in Obsidian. Use mid-workflow the moment something is wrong, ambiguous, slow, or could be better in a skill/agent/pipeline — or when the user says "log that / note that learning / capture this for the retro". Quick append only; /pumpd-retro reviews these later and turns them into improvements.
