5c2901ae27 docs(context): fix unrunnable ContextGraph docstring example (#921)
* docs(context): fix unrunnable ContextGraph docstring example

The module docstring's Example Usage block called add_node/add_edge with
keyword arguments they do not accept. add_node(node_id, node_type, ...) takes
node_type positionally and has no properties parameter, so the documented call
raised TypeError; add_edge's parameter is edge_type, so type= fell through to
**properties and polluted edge metadata while appearing to work.

Two of the three broken forms failed silently rather than raising, storing a
nested properties dict or a stray type key instead of erroring.

Add regression tests that execute the documented calls and assert the docstring
itself does not reintroduce the invalid kwargs.

* test(context): close two blind spots in the docstring regression guards

The guards added in the previous commit could pass while checking nothing.

_example_block() terminated the capture at the first "\n\n". The Example
Usage block already contains ">>> " spacer lines, so any reformatting that
turned one into a bare blank line would truncate the capture -- potentially
to empty -- and the guards would then scan a block that no longer held the
add_node/add_edge calls they exist to police.

Both guards also iterated over re.findall() without asserting a match. Zero
matches meant zero assertions and a green test, so the two failure modes
compounded: a truncated block produced no matches, and no matches produced
a pass.

Terminate the block at the next top-level section header (^\S) or end of
docstring instead, so blank lines inside the example are harmless, and
assert the captured block, the parsed statement list, and each guard's
match list are all non-empty.

Extract statements with doctest.DocTestParser rather than a line regex.
This also catches a call reformatted across "..." continuation lines, which
the ">>> graph.add_node(.*" pattern silently skipped, and lets
test_documented_calls_execute exec the docstring's own statements instead
of a retyped copy that could drift from it. Full doctest.testmod isn't
usable here: add_node/add_edge return True and the docs carry no
expected-output lines, so it reports 4 spurious failures.

Narrow the kwarg check to (?<![\w])type\s*= so a legitimate node_type=
or edge_type= in the docs no longer trips a guard aimed at bare type=.

Verified by mutating the module docstring and re-running the guards: extra
blank lines with a valid example still pass; regressed add_node/add_edge,
a type= on a continuation line, deleted calls, and a deleted section all
fail; a legitimate node_type= passes. 6 passed.
