#1831 — `graphify export graphml` crashed on any dict/list-valued
attribute (per-node metadata dict, graph-level hyperedges list) because
nx.write_graphml only accepts scalars; a real ~2,300-node graph failed
every export and left a 0-byte .graphml behind. to_graphml now coerces
None->"" and JSON-serializes non-scalars across graph/node/edge scopes
(int/float/bool/str pass through), and writes atomically via a temp file
so a failed export can't leave a partial file. Closes#1830.
#1807 followup — adopt @varuntej07's explicit in-guard sys.stdout.flush()
from #1811: piped stdout is block-buffered, so a small fully-buffered
output would only flush at interpreter shutdown (outside the guard),
where a closed-pipe reader escapes as a noisy shutdown error and nonzero
exit. Flushing inside the try closes that gap. Closes#1811.

#1807 — piping graphify into a reader that stops early (head,
Select-Object -First N, sed q) disconnected stdout mid-write, raising an
unhandled BrokenPipeError (OSError(EINVAL) on Windows) and exiting 255,
so CI wrappers and agent harnesses read a successful query as a failure.
The console entry point now wraps the CLI body: a closed-pipe reader is
treated as success — stdout is redirected to devnull so shutdown flush
can't raise again, and the process exits 0. Adds a subprocess regression
test.
#1804 — .nox/ (nox virtualenvs, tox's successor, same .nox/ tree shape)
was missing from _SKIP_DIRS while .tox was present, so nox site-packages
got fully indexed (one repo came out 91% venv noise). Added next to .tox
with a regression test.
