Fix memory_update: forward item_id by keyword in memU SQLite monkeypatch

[pufit]

Problem

The memory_update tool (memU item update) silently failed for every update, returning Failed to update memory <id> instead of surfacing an error.

Root cause: the vector-index monkeypatch in nerve/memory/memu_bridge.py wraps SQLiteMemoryItemRepo.update_item and forwarded item_id positionally:

def _indexed_update_item(self, item_id, *args, **kwargs):
    result = _original_update_item(self, item_id, *args, **kwargs)  # positional

But memu-py==1.4.0 declares update_item(self, *, item_id, ...) — item_id is keyword-only. The wrapper therefore called the original with self + item_id as two positionals, raising:

SQLiteMemoryItemRepo.update_item() takes 1 positional argument
but 2 positional arguments (and 3 keyword-only arguments) were given

update_item() in the bridge catches that TypeError and returns False, so the tool reported a silent failure rather than raising. delete_item(self, item_id) is not keyword-only, so the identical wrapper pattern worked there — which is why deletes succeeded and masked the bug. This has been latent since the memu-py==1.4.0 pin.

Fix

Forward args verbatim (matching the sibling _numpy_create_item wrapper) and derive item_id from kwargs/args for the index hook:

def _indexed_update_item(self, *args, **kwargs):
    result = _original_update_item(self, *args, **kwargs)
    item_id = kwargs.get("item_id", args[0] if args else None)
    ...

Tests

Added TestIndexedUpdateItemForwarding in tests/test_memu_bridge.py:

• Guards that memu's update_item is keyword-only (catches future signature drift).
• Exercises the real _patch_sqlite_bugs wrapper with a keyword-only spy original and asserts item_id is forwarded by keyword without a TypeError (restores global state afterward).

Full suite: 1158 passed, 2 skipped.
