Alice in wonderland expensive to process, plus Azure OpenAI flags it as
inappropriate content. Changed this to a smaller file about quantum
computers.

> [!NOTE]
> Update vector search limit-none tests to use local quantum/NLP files
and add `test_data/Quantum_computers.txt`, adjusting queries
accordingly.
>
> - **Tests**:
> - **Vector engine limit-none coverage**
(`test_vector_engine_search_none_limit`):
> - Replace `examples/data/alice_in_wonderland.txt` with
`tests/test_data/Quantum_computers.txt` and
`tests/test_data/Natural_language_processing.txt` across
`cognee/tests/test_chromadb.py`, `cognee/tests/test_lancedb.py`, and
`cognee/tests/test_pgvector.py`.
> - Update query to "Tell me about Quantum computers" and keep assertion
verifying no implicit `limit` (ensure `len(result) > 15`).
> - **Test data**:
> - Add `cognee/tests/test_data/Quantum_computers.txt`.

> [!NOTE]
> Standardizes vector search to accept `limit=None` (fetch all/count),
updates adapters/interface and retrievers, and adds tests plus minor
logging/doc assets.
>
> - **Vector search API**:
> - Change `limit` to `Optional[int]` in `vector_db_interface` and
adapters (`ChromaDBAdapter`, `LanceDBAdapter`, `PGVectorAdapter`,
`NeptuneAnalyticsAdapter`).
> - Behavior: `limit=None` fetches all/collection count; early-return on
`limit<=0`; minor logging copy/level tweaks; `PGVector` counts via
`func.count`.
> - **Retrievers**:
> - Switch internal calls to `limit=None` (`CogneeGraph`,
`temporal_retriever`, brute-force triplet search).
> - **Tests**:
> - Add `limit=None` coverage for ChromaDB, LanceDB (new suite), and
PGVector; assert results exceed default caps.
> - **Examples/Docs**:
> - Demo script prunes before run; add tutorial notebook and data
assets; remove one markdown article.
> - **Misc**: LLM utils demote a log line to `debug`.

Until now, limit=0 in vector search meant that there is no limit and we
should return everything. This caused confusion and errors, so now it is
reworked so that limit=None means no limit on the search. If someone
puts limit=0, there will be no results returned, as it makes more sense
and is less error prone.

## Description
Removed default user creation during brute force search. Even when a
user is provided to search it's not forwarded to the Retrievers, the
retrievers always created a default user and sent telemetry as the
default user which is inaccurate, they also create a default user even
when there shouldn't be one.
if this information is necessary for telemetry we should forward the
user information that was sent through search through the retrievers and
not always create a default user
