vault-code-learn

The missing code-learning loop. At session start (or on demand via /code-learn) walks the active repo(s) under ~/Documents/GitHub/, extracts a durable pattern digest — tech stack and dependency signatures, naming conventions, error-handling style, test patterns, lint/type rules, file-layout idioms, frequent imports, and what the repo intentionally does NOT use — and writes one digest per repo to MoxyWolf Vault/_Shared Knowledge/Code Patterns/<repo>.md. Incremental: only files modified since the digest's last-learned timestamp are re-read. The digest is referenced by future Claude sessions so suggestions match the team's existing patterns instead of generic boilerplate. Auto-invoked by /session-start; manual trigger via /code-learn <repo> | --project <slug> | --all. v0.1.0.
