fix(graphify): update CLI invocation from legacy flag form to subcommand

graphify . --update was removed in favor of graphify update . in v0.4.x.
Also improves version detection to try `graphify --version` before
falling back to python3 importlib query.

Closes #2732

 1. **Invoke graphify:**
    Run from the project root:
    ```
-   graphify . --update
+   graphify update .
    ```
    This builds the knowledge graph with SHA256 incremental caching.
    Timeout: up to 5 minutes (or as configured via graphify.build_timeout).
