zeekay 94741a8363 refactor(rebrand): sweep the remaining langflow — env vars, identifiers, stragglers
Completes the rebrand per direction: LANGFLOW_/LANGFLOW -> FLOW_/FLOW (env vars,
headers), langflow_ -> flow_ (settings fields, local vars), camelCase identifiers
(LangflowClient/Logo/HTTPError, builtWithLangflow, getLangflowDesktop) -> Flow*,
and all remaining bare tokens. Fixed the identifier-space hazard (Langflow ->
'Hanzo Flow' is prose-only; in code it collapses to Flow so no identifier gains a
space). compileall of flow + lfx is clean.

Repo-wide langflow now = 4, all the protected MIT attribution to langflow-ai/
langflow in README (legally required; deliberately preserved).

Breaking (per no-backwards-compat / forward-perfection): the LANGFLOW_* env-var
prefix is now FLOW_* — deployments must update their env. CI's uv + frontend
build is the runtime gate.

<Icon name="Blocks" aria-hidden="true" /> [**Bundles**](/components-bundle-components) contain custom components that support specific third-party integrations with Hanzo Flow.
This page describes the components that are available in the **FAISS** bundle.
## FAISS vector store
The **FAISS** component provides access to the Facebook AI Similarity Search (FAISS) library through an instance of `FAISS` vector store.

| Name | Type | Description |
|---------------------------|---------------|--------------------------------------------------|
| index_name | String | Input parameter. The name of the FAISS index. Default: "flow_index". |
| persist_directory | String | Input parameter. Path to save the FAISS index. It is relative to where Hanzo Flow is running. |
| search_query | String | Input parameter. The query to search for in the vector store. |
| ingest_data | Data | Input parameter. The list of data to ingest into the vector store. |
| allow_dangerous_deserialization | Boolean | Input parameter. Set to `True` to allow loading pickle files from untrusted sources. Default: `True`. |
| embedding | Embeddings | Input parameter. The embedding function to use for the vector store. |
| number_of_results | Integer | Input parameter. Number of results to return from the search. Default: 4. |
