Codex-compatible ToolHandler trait and types

This module implements the handler pattern from OpenAI’s Codex project, providing a more modular and composable approach to tool execution.

Key patterns from Codex:

  • ToolHandler trait with kind/matches_kind/is_mutating/handle methods
  • ToolKind enum for categorizing tool types
  • ToolPayload for typed tool arguments
  • ToolOutput for structured tool results
  • ToolInvocation for execution context
