v1.1.12

Features

• Agent: Added support for dynamically created sub-agents to forward runtime events directly into the parent agent event stream, so callers can observe child-agent progress, tool activity, and final outputs without waiting for the whole delegated task to finish.
• Agent: Added dynamic sub-agent creation support, allowing agents to create and use child agents at runtime for more flexible task decomposition and delegation.
• Goal: Added Goal support aligned with the Go implementation, giving agents a structured way to carry task objectives through the execution flow.
• A2A: Added optional app_name support to TrpcA2aAgentService, allowing the Runner app identity to differ from the exposed A2A service name while keeping the existing service_name fallback behavior.
• Session: Updated list_sessions() so user_id can be omitted. When user_id=None, InMemory, SQL, Redis, and Eval session services now return all sessions under the specified app_name without loading session events.
• Skill: Added the skills_hub module to support centralized skill discovery and management.

Bug Fixes

• Graph: Fixed GraphAgent AgentNode.last_response so it no longer records thinking text or intermediate tool-call round text as the node's final response. The graph now uses Event.is_final_response() and removes thinking content before saving the last response.
• A2A: Fixed internal pipeline example scripts and paths so the example workflow can be triggered and run with the expected files.
• Docs: Fixed README optional dependency installation commands by quoting extras, removing extra spaces, and normalizing package-extra casing so shell parsing works correctly.

Docs

• Docs: Added MkDocs site entry pages and navigation for the existing English and Chinese documentation, plus a GitHub Pages workflow so the README documentation badge can point to a published documentation site.
• Docs: Added documentation and test coverage for listing sessions across all users under an app by passing user_id=None.

Internal

• CI: Added and adjusted internal pipeline test trigger files used by repository automation.
