### What problem does this PR solve?

## Cause of the bug:
During the execution process, due to improper use of trio
CapacityLimiter, the configuration parameter MAX_CONCURRENT_TASKS is
invalid, causing the executor to take out a large number of tasks from
the Redis queue at one time.

This behavior will cause the task executor to occupy too much memory and
be killed by the OS when a large number of tasks exist at the same time.
As a result, all executing tasks are suspended.

## Fix:
Added the task_manager method to the entry of /rag/svr/task_executor.py
to make CapacityLimiter effective. Deleted the invalid async with
statement.

## Fix result:
After testing, the task executor execution meets expectations, that is:
concurrent execution of up to $MAX_CONCURRENT_TASKS tasks.

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:

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

Deprecate `/github_callback` route in favor of
`/oauth/callback/<channel>` for GitHub OAuth integration:

- Added GitHub OAuth support in the authentication module
- Introduced `GithubOAuthClient` with methods to fetch and normalize
user info
  - Updated `CLIENT_TYPES` to include GitHub OAuth client
- Deprecated `/github_callback` route and suggested using the generic
`/oauth/callback/<channel>` route

### Usage

- [Create a GitHub OAuth
App](https://github.com/settings/applications/new) to obtain the
`client_id` and `client_secret`, configure the authorization callback
url: `https://your-app.com/v1/user/oauth/callback/github`
- Edit `service_conf.yaml.template`:
  ```yaml
  # ...
  oauth:
    github:
      type: "github"
      icon: "github"
      display_name: "Github"
      client_id: "your_client_id"
      client_secret: "your_client_secret"
      redirect_uri: "https://your-app.com/v1/user/oauth/callback/github"

* Adds `mcp.server` package
* Resolves "warning: package would be ignored" ambiguity by changing
`sdk` to `sdk.python.ragflow_sdk`
* Resolves "error: package directory 'intergrations' does not exist" by

Add frontend support for third-party login integration:

- Used `getLoginChannels` API to fetch available login channels from the
server
- Used `loginWithChannel` function to initiate login based on the
selected channel
- Refactored `useLoginWithGithub` hook to `useOAuthCallback` for
generalized OAuth callback handling
- Updated the login page to dynamically render third-party login buttons
based on the fetched channel list
- Styled third-party login buttons to improve user experience
- Removed unused code snippets

> This PR removes the previously hardcoded GitHub login button. Since
the functionality only worked when `location.host` was equal to
`demo.ragflow.io`, and the authentication logic is now based on
`login.ragflow.io`, this change does not affect the existing logic and
is considered a non-breaking change
