Function format_learnings_markdown

atomic-agent/src/learnings.rs:160–185

Format learnings as individual list items grouped by category. Only includes **Repo** and **Workflow** learnings. Code learnings (with file:line references) are stored in the change's unhashed section, not in the context file — they're noisy, they drift with edits, and in a large project they'd grow unbounded. Returns a map of heading → list items so callers can merge into existing headings inst
