Changelog

New Features:

GitHub App Authentication for Knowledge Sources: Adds support for authenticating with GitHub as a GitHub App (app_id, installation_id, private_key) in addition to personal access tokens, with thread-safe token caching and both sync/async variants.
File Upload: Added image/heic and image/heif support to file upload endpoints.
Approvals: Added approval status endpoint and admin-gated continue run enforcement.
Traces: Added advanced filtering DSL support in Agent OS

Google Tools: Restructured Google tools into agno.tools.google sub-package (from agno.tools.google import GmailTools). Old import paths still work with a backwards compatibility.
Team Task Mode:
- Enhances TeamMode.tasks streaming to provide structured task data for frontend rendering in events like TeamTaskCreated and TeamTaskUpdated
- Structured task data in TaskStateUpdatedEvent: Added tasks: List[TaskData] field containing full task details (id, title, description, status, assignee, dependencies, result) and completion_summary field

OpenAI Responses:
- Fixed vector store polling race condition where file_search silently returned empty results due to eventual consistency in OpenAI's vector_stores.files.list
  API.
- Added input_file support to OpenAIResponses
Sentence Transformer Reranker: Fixed VRAM memory leak in SentenceTransformerReranker caused by CrossEncoder being instantiated on every _rerank() call instead of being reused.
