Ports two changes from the knowledge-base vault this skeleton is extracted
from, keeping the shared scripts byte-identical across the pair:
- `graph_summary` reports `by_tag` and `tag_count`, sized by `topTags`, and
drops the `by_type`/`by_status` breakdowns. An MCP-only agent could not
otherwise discover the tag spellings that `graph_search_nodes` matches
verbatim.
- `generate-graph.py --validate` now enforces a controlled vocabulary for a
note's `type`, which is where the drift signal `by_type` used to give now
lives. `AGENT_QUERY_GUIDE.md`, both skills and the-knowing-one quote the
enforced enum.
`tests/test_generate_graph.py` is new; `make test` is 50 tests. Regenerating
the graph also drops a stale `GLOBAL_AGENTS` node for a file this skeleton
does not carry.
