filter_applicable's per-intent try/except only caught (ValueError, TypeError),
so a hallucinated insert_between with a non-dict edge arg raised an uncaught
AttributeError and crashed the whole advance instead of being rejected by the
dry-run. Broaden to except Exception (ruff does not flag it, so no noqa is
added). Add a regression test for the string-edge case.
Also update llm_agent.py's stale module docstring (Fix cognition is now real,
not delegated; Protocol has 14 methods, not 13) and fix a stray closing paren
in a test_handlers_fix.py comment.

Behavior-preserving code-quality cleanup across the Dify Builder engine:
extract emit_canvas, build_change_set, mint_checkpoint, action_kind, and
merge_known_keys into handlers_fix.py (shared by handlers_build.py and
handlers_edit.py); extract _add in repository.py for the id-preservation
idiom; extract _make_edge (and unify the node/edge id-collision loops
into _next_unique_id) in graph_ops.py; extract _sync_graph_only in
dify_port.py. No behavior, generated ids, or wire output changed — same
387-test suite passes, ruff clean.
