**Fix: Prevent Flask hot reload from hanging due to early thread
startup**

### What problem does this PR solve?

When running the Flask server with `use_reloader=True` (enabled during
debug mode), modifying a Python source file would trigger a reload
detection (`Detected change in ...`), but the application would hang
instead of restarting cleanly.

This was caused by the `update_progress` background thread being started
**too early**, often within the main module scope.
This issue was reported in
[#7498](https://github.com/infiniflow/ragflow/issues/7498).

### Type of change

- [x] Bug Fix (non-breaking change which fixes an issue)
---

**Summary of changes:**
- Wrapped `update_progress` launch in a `threading.Timer` with delay to
avoid premature thread execution.
- Marked thread as `daemon=True` to avoid blocking process exit.
- Added `WERKZEUG_RUN_MAIN` environment check to ensure background
threads only run in the reloader child process (the actual Flask app).
- Retained original behavior in production mode (`debug=False`).

If the name field is not specified, Docker Compose will default to using
`docker` as the project name. This may cause conflicts with other
default projects, leading to unintended operations when executing
`docker compose` commands.

### What problem does this PR solve?

When executing Docker Compose commands, interference occurs between
multiple default projects, leading to operational chaos.​

When deleting knowledge base documents in RAGFlow, the current process

…sing the SDK chat API

### What problem does this PR solve?

When using the SDK for chat, you can include the IDs of additional
knowledge bases you want to use in the request. This way, you don’t need
to repeatedly create new assistants to support various combinations of
knowledge bases. This is especially useful when there are many knowledge
bases with different content. If users clearly know which knowledge base
contains the information they need and select accordingly, the recall
accuracy will be greatly improved.

Users only need to add an extra field, a kb_ids array, in the HTTP
request. The content of this field can be determined by the client
fetching the list of knowledge bases and letting the user select from
it.

### Type of change
- [x] Bug Fix (non-breaking change which fixes an issue)

### What problem does this PR solve?

**Issue Description:**

When using the `/api/retrieval` endpoint with a POST request and setting
the `keyword` parameter to `true`, the system invokes the
`model_instance` method from `TenantLLMService` to create a `chat_mdl`
instance. Subsequently, it calls the `keyword_extraction` method to
extract keywords.

However, within the `keyword_extraction` method, the `chat` function of
the LLM attempts to access the `chat_mdl.max_length` attribute to
validate input length. This results in the following error:

```
AttributeError: 'SILICONFLOWChat' object has no attribute 'max_length'
```

**Proposed Solution:**

Upon reviewing other parts of the codebase where `chat_mdl` instances
are created, it appears that utilizing `LLMBundle` for instantiation is
more appropriate. `LLMBundle` includes the `max_length` attribute, which
should resolve the encountered error.

### What problem does this PR solve?

There are two main changes:

1. Update xgboost to 1.6.0 to build the project on MacOS with Apple
chips, this change refers to the issue:
https://github.com/infiniflow/ragflow/issues/5114.

2. When `use_china_mirrors` is set in `download_deps.py`, the names of
chrome files downloaded by the script will be different from the file
names used in Dockerfile, so I added the file name in `get_urls`
function to solve this problem.

I think it's better to add testing for Docker image
`infiniflow/ragflow_deps` to the test workflow, but since the workflow
is currently running on a self-hosted runner, I'm not sure how to modify
it.

### Introduction
I fixed the problems when using OpenSearch as the DOC_ENGINE, the
failures of pytest and the wrong API's return.
Mainly about delete chunk, list chunks, update chunk, retrieval chunk.
The pytest comand "cd sdk/python && uv sync --python 3.10 --group test
--frozen && source .venv/bin/activate && cd test/test_http_api &&
DOC_ENGINE=opensearch pytest test_chunk_management_within_dataset -s
--tb=short " is finally successful.

###Others
As some changes between Elasticsearch And Opensearch differ, some pytest
results about OpenSearch are correct and resonable. However, some pytest
params (skipif params) are incompatible. So I changed some pytest params
about skipif.

As a search engine programmer, I will still focus on the usage of vector
databases (especially OpenSearch) for the RAG stuff.
Thanks for your review
