Devin AI 24e8ff6c90 feat: Add crew-level before_tool_call and after_tool_call governance hooks ...

Adds optional before_tool_call and after_tool_call callback parameters to the
Crew class, enabling per-crew governance middleware for tool call authorization.

- before_tool_call(agent, tool_name, tool_input): Runs before each tool
  execution. Raise an exception to block the call.
- after_tool_call(agent, tool_name, tool_input, tool_output): Runs after
  each tool execution for audit/logging.

These crew-level hooks complement the existing global hook system, scoping
governance policies to individual crew instances.

Closes #5888
