DELETE /library/api/libraries/{uid}/ called bare lib.delete(), orphaning
Collections/Items/Chunks/Images and skipping Concept GC — the only delete
path not using the shared cascade. It now delegates to
delete_library_cascade like the HTML and workspace delete paths.
Name-conflict checks on both create endpoints are now case-insensitive
via find_library_by_name_ci (parameterised Cypher toLower comparison —
not neomodel iexact, which embeds the value in a regex and breaks on
names like "C++ Notes"). The Neo4j unique index is case-sensitive, so
"amazon connect" previously coexisted silently with "Amazon Connect",
confusing every name-matching client (Spelunker matches names
case-insensitively). The 409 reports the existing spelling. The plain
create also gains a UniqueProperty catch for the pre-check/save race,
mirroring the workspace path.
