What's broken

cgc visualize's live web graph renders no edges on FalkorDB — CGC's default backend on Unix under Python 3.12+.

parse_element in viz/server.py classified relationships by class name:

elif type_name in ('Relationship', 'KuzuRelationship') or is_dict_rel:

FalkorDB's edge class is named Edge. It matched no branch, is not a dict, and was silently discarded. parse_rel directly below already reads FalkorDB edges correctly — it was simply never reached.

Confirmed against the real falkordb package:

>>> type(edge).__name__, hasattr(edge, "type"), hasattr(edge, "relation")
('Edge', False, True)

>>> server.parse_element(edge, nodes, edges); edges
[]                        # while parse_rel(edge) directly -> the correct edge

Nodes were unaffected — falkordb's node class is named Node, which the old check listed.

Fix

The offline renderer in cli_helpers.py already classified by duck typing and handled this (#1453). Both renderers now share those predicates in utils/graph_shapes.py, so classification cannot drift apart again. Id and property extraction stay duplicated — deliberately out of scope here.

New regression test asserts the FalkorDB edge survives parse_element, plus node/relationship classification across Neo4j, FalkorDB, Kùzu and Ladybug shapes. Reverting only viz/server.py makes it fail with nodes present and edges == [].

parse_element classified relationships by class name, matching only
Relationship/KuzuRelationship. FalkorDB's edge class is named Edge, so it
matched no branch and every FalkorDB relationship was silently dropped —
on the backend that is CGC's default on Unix under Python 3.12+. parse_rel
directly below already reads FalkorDB edges correctly; it was never reached.

The offline renderer in cli_helpers already classified by duck typing and
handled this (CodeGraphContext#1453). Both renderers now share those predicates in
utils/graph_shapes, so classification cannot drift apart again.

Verified on a local trial-merge: consolidating the backend duck-typing into graph_shapes.py removes the cli_helpers/viz duplication that let the two paths drift (which is exactly how FalkorDB's Edge class fell through the viz classifier while the offline renderer worked), the FalkorDB attribute checks (relation/src_node before dict fallbacks) are ordered correctly, and the 152-line test file covers every backend's shape including the Kùzu-vs-Ladybug case-spelling split. Merges cleanly over today's #1682 module-label work in the same files. Full suite green (1455, +11). Thanks @OfficialAbhinavSingh!

* feat: add SSL connection parameters to cassandra_ingester.py

* fix(jobs): serialize last update time in job responses (#1679)

* fix(cli): explain embedded database lock conflicts (#1684)

* fix(setup-wizard): stop replacing IDE settings that are JSONC (#1677)

VS Code and its forks write settings.json as JSONC. json.load rejects comments
and trailing commas, and the wizard treated that rejection as "no settings yet"
before writing the file back, so a user's whole configuration was replaced by a
lone mcpServers key.

Parse JSONC before giving up, and if the file still cannot be parsed, leave it
alone instead of overwriting it. Back up the file before writing either way, and
say so when comments are present, since json.dump cannot preserve them.

Fixes #660

* feat(cgcignore): treat .gitignore as an ignore source (#1680)

Anything git ignores is now ignored by the indexer, so a repository no longer
needs a .cgcignore that restates its .gitignore.

Patterns are layered defaults -> .gitignore -> .cgcignore. Matching is
last-match-wins, so a negated pattern in .cgcignore can still bring a
git-ignored path back into the graph.
