• Python: [BREAKING] PR2 — Wire context provider pipeline, remove old types, update all consumers (#3850)

  * PR2: Wire context provider pipeline and update all internal consumers
  
  - Replace AgentThread with AgentSession across all packages
  - Replace ContextProvider with BaseContextProvider across all packages
  - Replace context_provider param with context_providers (Sequence)
  - Replace thread= with session= in run() signatures
  - Replace get_new_thread() with create_session()
  - Add get_session(service_session_id) to agent interface
  - DurableAgentThread -> DurableAgentSession
  - Remove _notify_thread_of_new_messages from WorkflowAgent
  - Wire before_run/after_run context provider pipeline in RawAgent
  - Auto-inject InMemoryHistoryProvider when no providers configured
  
  * fix: update all tests for context provider pipeline, fix lazy-loaders, remove old test files
  
  * refactor: update all sample files for context provider pipeline (AgentThread→AgentSession, ContextProvider→BaseContextProvider)
  
  * fix: update remaining ag-ui references (client docstring, getting_started sample)
  
  * fix: make get_session service_session_id keyword-only to avoid confusion with session_id
  
  * refactor: rename _RunContext.thread_messages to session_messages
  
  * refactor: remove _threads.py, _memory.py, and old provider files; migrate devui to use plain message lists
  
  * rename: remove _new_ prefix from test files
  
  * refactor: rewrite SlidingWindowChatMessageStore as SlidingWindowHistoryProvider(InMemoryHistoryProvider)
  
  * fix: read full history from session state directly instead of reaching into provider internals
  
  * fix: update stale .pyi stubs, sample imports, and README references for new provider types
  
  * fix: remove stale message_store, _notify_thread_of_new_messages, and session_id.key references in samples
  
  * refactor: merge context_providers and sessions sample folders into sessions, remove aggregate_context_provider
  
  * refactor: UserInfoMemory stores state in session.state instead of instance attributes
  
  * feat: add Pydantic BaseModel support to session state serialization
  
  Pydantic models stored in session.state are now automatically serialized
  via model_dump() and restored via model_validate() during to_dict()/from_dict()
  round-trips. Models are auto-registered on first serialization; use
  register_state_type() for cold-start deserialization.
  
  Also export register_state_type as a public API.
  
  * fix mem0
  
  * Update sample README links and descriptions for session terminology
  
  - Replace 'thread' with 'session' in sample descriptions across all READMEs
  - Update file links for renamed samples (mem0_sessions, redis_sessions, etc.)
  - Fix Threads section → Sessions section in main samples/README.md
  - Update tools, middleware, workflows, durabletask, azure_functions READMEs
  - Update architecture diagrams in concepts/tools/README.md
  - Update migration guides (autogen, semantic-kernel)
  
  * Fix broken Redis README link to renamed sample
  
  * Fix Mem0 OSS client search: pass scoping params as direct kwargs
  
  AsyncMemory (OSS) expects user_id/agent_id/run_id as direct kwargs,
  while AsyncMemoryClient (Platform) expects them in a filters dict.
  Adds tests for both client types.
  
  Port of fix from #3844 to new Mem0ContextProvider.
  
  * Fix rebase issues: restore missing _conversation_state.py and checkpoint decode logic
  
  - Add back _conversation_state.py (encode/decode_chat_messages) lost in rebase
  - Fix on_checkpoint_restore to decode cache/conversation with decode_chat_messages
  - Fix on_checkpoint_restore to use decode_checkpoint_value for pending requests
  - Add tests/workflow/__init__.py for relative import support
  - Fix test_agent_executor checkpoint selection (checkpoints[1] not superstep)
  
  * Add STORES_BY_DEFAULT ClassVar to skip redundant InMemoryHistoryProvider injection
  
  Chat clients that store history server-side by default (OpenAI Responses API,
  Azure AI Agent) now declare STORES_BY_DEFAULT = True. The agent checks this
  during auto-injection and skips InMemoryHistoryProvider unless the user
  explicitly sets store=False.
  
  * Fix broken markdown links in azure_ai and redis READMEs
  
  * Fix getting-started samples to use session API instead of removed thread/ContextProvider API
  
  * updates to workflow as agent
  
  * fix group chat import
  
  * Rename Thread→Session throughout, fix service_session_id propagation, remove stale AGUIThread
  
  - Fix: Propagate conversation_id from ChatResponse back to session.service_session_id
    in both streaming and non-streaming paths in _agents.py
  - Rename AgentThreadException → AgentSessionException
  - Remove stale AGUIThread from ag_ui lazy-loader
  - Rename use_service_thread → use_service_session in ag-ui package
  - Rename test functions from *_thread_* to *_session_*
  - Rename sample files from *_thread* to *_session*
  - Update docstrings and comments: thread → session
  - Update _mcp.py kwargs filter: add 'session' alongside 'thread'
  - Fix ContinuationToken docstring example: thread=thread → session=session
  - Fix _clients.py docstring: 'Agent threads' → 'Agent sessions'
  
  * Fix broken markdown links after thread→session file renames
  
  * fix azure ai test

• Python: restructure: Python samples into progressive 01-05 layout (#3862)

  * restructure: Python samples into progressive 01-05 layout
  
  - 01-get-started/: 6 numbered steps (hello agent → hosting)
  - 02-agents/: all agent concept samples (tools, middleware, providers, etc.)
  - 03-workflows/: ALL existing workflow samples preserved as-is
  - 04-hosting/: azure-functions, durabletask, a2a
  - 05-end-to-end/: demos, evaluation, hosted agents
  - Old files moved to _to_delete/ for review
  - Added AGENTS.md with structure documentation
  - autogen-migration/ and semantic-kernel-migration/ preserved at root
  
  * fix: switch to AzureOpenAI Foundry, fix CI failures
  
  - Switch all 01-get-started samples to AzureOpenAIResponsesClient with
    Azure AI Foundry project endpoint (AZURE_AI_PROJECT_ENDPOINT +
    AZURE_OPENAI_RESPONSES_DEPLOYMENT_NAME + AzureCliCredential)
  - Add _to_delete/ and 05-end-to-end/ to pyrightconfig.samples.json excludes
  - Fix test paths in packages/ that referenced old getting_started/ dirs:
    durabletask conftest + streaming test, azurefunctions conftest,
    devui conftest + capture_messages + openai_sdk_integration
  - Fix workflow_as_agent_human_in_the_loop.py import (sibling import)
  - Update hosting READMEs and tool comment paths
  - Replace root README.md with new structure overview
  - Update AGENTS.md to document Azure OpenAI Foundry as default provider
  
  * cleanup: remove _to_delete folder, copy resource files to active dirs
  
  All files in _to_delete/ were either:
  - Exact duplicates of files in the new structure (240 files)
  - Same file with only comment path updates (100 files)
  - One import-fix diff (workflow_as_agent_human_in_the_loop.py)
  - One superseded minimal_sample.py
  
  Resource files (sample.pdf, countries.json, employees.pdf, weather.json)
  copied to 02-agents/sample_assets/ and 02-agents/resources/ since active
  samples reference them.
  
  * fix: address PR review comments, centralize resources, remove root duplicates
  
  - Fix type annotation in 04_memory.py (string union -> proper types)
  - Fix old sample paths in observability files
  - Fix grammar/spelling in observability samples
  - Move sample_assets/ and resources/ to shared/ folder
  - Remove 8 duplicate observability files from 02-agents root
  - Update resource path references in multimodal_input and provider samples
  
  * fix: update broken links from old getting_started paths to new structure
  
  - Update relative paths in READMEs: getting_started/ → 01-get-started/,
    02-agents/, 03-workflows/, 04-hosting/, 05-end-to-end/
  - Fix absolute GitHub URLs in package READMEs
  - Fix broken link in ollama package README
  
  * fix: convert absolute GitHub URLs to relative paths for link checker
  
  Absolute URLs to python/samples/ on main branch 404 until PR merges.
  Converted to relative paths that linkspector can verify locally.
  
  * fix: update link for handoff sample moved to orchestrations/
  
  * fix: update chatkit-integration README path from demos/ to 05-end-to-end/
  
  * fix: update broken links in orchestrations README to match flat directory structure
