Implementation notes (heuristics):
- Type inferred from file paths + diff keywords + add/delete ratio
- Scope prefers 'goal' when goal/* is touched; otherwise based on top-level dirs
- For <=6 files: generate short per-file notes from added lines (defs/classes/click options/headings)
- A/M/D derived from git name-status; per-file +X/-X from git numstat
