Function dedup_learnings

atomic-agent/src/learnings.rs:313–338

Remove learnings that already exist in the context file. Returns a new `Learnings` with only the Repo and Workflow entries that are not already present. Code learnings are always empty in the result because they're not written to context files. Comparison is by finding text (exact match on the list item content).
