[BUG]Hierarchical Manager assigned wrong tools

[andrewn3]

Description

When you have a hierarchical process and the first agent has tools assigned, it seems that the task fot this agent is assigned these tools, so when assigning tools to the manager these task tools are also included in the list of tools a manager can use (I assume it would be the same if the tools are also defined at a task level). This means that the manager will use these tools, in addition to the delegate and ask question tools. This means the manager can carry out the work with these tools rather than just delegating/asking. also if the agent has a different LLM defined then not good as lots of work is carried out by the manager.

Steps to Reproduce

1. Create a hierarchical process and use manager_llm
2. Create the first agent with tools assigned, create other agents with no tools.
3. Create a tasks with no tools.

Expected behavior

Unlike the planner agent which has it's own task, the manager agent picks up the first task and the tools associated with that. I would expect under all scenarios that just delegate and ask tools are assigned to the manager.

so it seems to happen is in crew.py it assigns the tools from task 1

tools_for_task = task.tools or agent_to_use.tools or []

which means this line adds the delegate and ask tools tools = self._inject_delegation_tools(tools, task.agent, [task.agent])

and then the manager does work with the tools from the first agent e.g. searching the internet etc rather than just delegating/asking questions.

Possible Solution

in crew.py this line tools_for_task = task.tools or agent_to_use.tools or [] should be changed to check if it's the manager and assign the agent tools only otherwise assign the task/agent or no tools
