fix(mypy): complete streaming.py type fixes (24→0 errors)
Resolved all remaining mypy errors in streaming.py by adding proper None checks, union type narrowing, and type annotations: - Fixed ToolContext None checks before accessing attributes - Added isinstance checks for OpenAIAssistantMessageParam before accessing tool_calls - Added None checks for response_tool_call and tool_call.function - Fixed AllowedToolsFilter attribute access (allowed/disallowed) - Added explicit type annotations to ensure str types (not str | None) - Added type ignore comments for dict/TypedDict compatibility issues All meta reference agent files now pass mypy with 0 errors (down from 280 errors). 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
