Bug: _find_checkpoint() glob paths are relative to process cwd — ML path silently disabled outside repo root

[bradsmithmba]

Summary

_find_checkpoint() uses glob.glob('models/checkpoints/best_model.pth') and similar relative paths. When the process is launched from any directory other than the repo root (e.g., the CLI is run from ~ or a different project dir), all patterns match nothing and the function returns None, silently forcing the heuristic path every time.

Evidence

src/api/enhanced_strategy_recommender.py lines 113-118: five glob.glob() calls with relative path strings, no Path(__file__) anchor.

Fix

Anchor to the module's own location:

repo_root = Path(__file__).parents[3]
patterns = [str(repo_root / p) for p in [...]]
