Joao Moura ef8b2ba03b feat: add support for agents to invoke Flows as tools ...

- Add FlowTool(BaseTool) in crewai/tools/flow_tool.py that wraps a Flow
  class as a callable tool (instantiates, calls kickoff, returns result)
- Add create_flow_tools() helper to convert list of Flow classes to tools
- Add Agent.flows parameter (list of Flow classes)
- Wire _set_flow_tools() into Agent.post_init_setup to auto-convert
  flows into tools and merge them into the agent's tool list
- Export FlowTool and create_flow_tools from crewai/__init__.py
- Add comprehensive tests (14 tests covering unit + integration)
