merge: track H group N

The merge agent stopped this branch on an add/add conflict it had not been
told to expect: groups U and N each created tests/test_understand_tools.py.
Resolved by hand:
- tests/test_understand_tools.py stays U's (the drawing_understand wire
  tests), and N's takeoff wire tests move whole to
  tests/test_understand_takeoff_tools.py. Each file keeps its own client
  fixture: U's opens a fresh document, N's reads files only.
- server.py: SECTION 26 (4 tools, U then D) is kept as merged, and SECTION
  27 (Plant Takeoffs, 2 tools) follows it whole, above the RESOURCES
  banner.
- discovery/aliases.py: additive; the two takeoff records follow the four
  readers.
- tests/test_tool_registry.py: all three branches' paragraphs are kept.
  The snapshot is recomputed from the live registry: analysis 18, 247
  tools. Task 11 ranks `understand` and `plant`.
- docs/tool-inventory.json regenerated (247 tools, 26 groups); README
  counts are 247 registered / 242 advertised. The collected-tests figure
  is left to Task 11.

ruff check passes. Suite: 4919 passed, 1 xfailed. The one deselected test
is the collected-tests figure.
