Joao Moura aee571b775 feat: add support for agents to invoke Flows as tools ...

Agents can now declare flows=[MyFlow] and invoke them as regular tools.
Each Flow class is wrapped as a FlowTool(BaseTool) — the agent decides
WHEN to use it (via tool selection), the Flow handles HOW (deterministic
execution).

- Add flows field to Agent
- Add FlowTool and create_flow_tools in tools/flow_tool.py
- Export from crewai.__init__
- 14 tests

No dependency changes. No memory changes. Just the flow-tool feature.
