Hey @rohityan, appreciate you taking the time.

This PR is a small, low-risk typing cleanup in agent_transfer.py There's no behavior changes.

What changed:

• Replaced loose Any types with the actual BaseAgent type for transfer target parameters.
• Changed list[...] to Sequence[...] where the code only reads the collection, better reflecting intent.
• Cleaned up TYPE_CHECKING imports to reference concrete modules (agents.base_agent, agents.llm_agent) instead of package-level re-exports.
• Removed quoted forward-ref strings ('LlmAgent', 'BaseAgent') now that from future import annotations makes them unnecessary
• Deleted two stale # TODO: Refactor the annotation comments that this change resolves. these functions previously accepted Any, so type checkers couldn't catch misuse of target_agent/target_agents. Now ca and the docstrings match reality instead of describing a duck-typed contract.

Risk: none functionally, this is annotations and imports only, no runtime logic touched.
