validate_extraction() is documented to return a list of error strings ("empty
list means valid"), but raised TypeError: unhashable type: 'list' when a node
id -- or an edge source/target -- was a non-hashable value such as a list. This
occurs in practice when an LLM extraction subagent emits malformed JSON like
{"id": ["foo", "bar"], ...}. Crash sites: the node_ids set comprehension and
the `edge[...] not in node_ids` membership tests.
Because build_from_json() validates at its start, a single malformed node
aborted the entire build, losing an otherwise-complete extraction of a large
corpus. build_from_json() itself would also raise (G.add_node(<list>) and the
`not in node_set` test) if the validator were bypassed.
- validate.py: build node_ids during the node pass, adding only hashable ids;
report a non-hashable id/endpoint as an error string instead of crashing.
All existing messages and the dangling-edge checks are preserved.
- build.py: skip dict nodes with a missing/non-hashable id and edges with
non-hashable endpoints (stderr warning). Non-dict nodes are deliberately
left to raise so the multigraph diagnostic still observes shape errors.
- tests: 3 cases in test_validate.py and 2 in test_build.py.
- build/validate: accept NetworkX <=3.1 "links" key alongside "edges" (#212)
- __main__: skip version check during install/uninstall, deduplicate paths (#220)
- all file IO: explicit encoding="utf-8" to prevent crashes on Windows CJK locales (#204)
- hooks: add newline="\n" on write to prevent CRLF shebang breakage on Windows (#204)
- export: strip trailing .md from safe_name so "CLAUDE.md" doesn't become "CLAUDE.md.md" (#221)
- report: add Community Hubs navigation block so Obsidian vault stays connected (#221)

style: replace all em dashes with hyphens
fix: explain hidden .graphify/ folder in skill output and README
fix: rename .graphify/ to graphify-out/ so output is visible by default
