e9ee897973 fix: resolve remaining CI failures for style checks and unit tests 
- Add model_features property and build_execution_context method to
  AgentAppRunner to fix mypy attr-defined errors
- Export WorkflowComment, WorkflowCommentReply, WorkflowCommentMention
  from models/__init__.py to fix import errors
- Add NestedNodeGraphRequest, NestedNodeGraphResponse,
  NestedNodeParameterSchema to services/workflow/entities.py
- Update test_agent_chat_app_runner: tests for invalid LLM mode and
  invalid strategy now reflect unified AgentAppRunner behavior
  (no longer raises ValueError for these cases)

77c182f738 feat(api): propagate all app features in transparent upgrade 
VirtualWorkflowSynthesizer._build_features() now extracts ALL legacy
app features from AppModelConfig into the synthesized workflow.features:

- opening_statement + suggested_questions
- sensitive_word_avoidance (keywords/API moderation)
- more_like_this
- speech_to_text / text_to_speech
- retriever_resource

Previously workflow.features was hardcoded to "{}", losing all these
features during transparent upgrade. Now AdvancedChatAppRunner's
moderation, opening text, and other feature layers work correctly
for transparently upgraded old apps.

7052257c8d fix(api): use lazy workflow persistence for transparent upgrade of old apps 
VirtualWorkflowSynthesizer.ensure_workflow() creates a real draft
workflow on first call for a legacy app, persisting it to the database.
On subsequent calls, returns the existing draft.

This is needed because AdvancedChatAppGenerator's worker thread looks
up workflows from the database by ID. Instead of hacking the generator
to skip DB lookups, we treat this as a lazy one-time upgrade: the old
app gets a real workflow that can also be edited in the workflow editor.

Verified: old chat app created on main branch ("What is 2+2?" -> "Four")
and old agent-chat app ("Say hello" -> "Hello!") both successfully
execute through the Agent V2 engine with AGENT_V2_TRANSPARENT_UPGRADE=true.

66212e3575 feat(api): implement zero-migration transparent upgrade (Phase 8) 
Add two feature-flag-controlled upgrade paths that allow existing apps
and LLM nodes to transparently run through the Agent V2 engine without
any database migration:

1. AGENT_V2_TRANSPARENT_UPGRADE (default: off):
   When enabled, old apps (chat/completion/agent-chat) bypass legacy
   Easy-UI runners. VirtualWorkflowSynthesizer converts AppModelConfig
   to an in-memory Workflow (start -> agent-v2 -> answer) at runtime,
   then executes via AdvancedChatAppGenerator. Falls back to legacy
   path on any synthesis error.

   VirtualWorkflowSynthesizer maps:
   - model JSON -> ModelConfig
   - pre_prompt/chat_prompt_config -> prompt_template
   - agent_mode.tools -> ToolMetadata[]
   - agent_mode.strategy -> agent_strategy
   - dataset_configs -> context
   - file_upload -> vision

2. AGENT_V2_REPLACES_LLM (default: off):
   When enabled, DifyNodeFactory.create_node() transparently remaps
   nodes with type="llm" to type="agent-v2" before class resolution.
   Since AgentV2NodeData is a strict superset of LLMNodeData, the
   mapping is lossless. With tools=[], Agent V2 behaves identically
   to LLM Node.

Both flags default to False for safety. Turn off = instant rollback.
46 existing tests pass. Flask starts successfully.

44491e427c feat(api): enable all sandbox/skill controller routes and resolve dependencies (P0) 
Resolve the full dependency chain to enable all previously disabled controllers:

Enabled routes:
- sandbox_files: sandbox file browser API
- sandbox_providers: sandbox provider management API
- app_asset: app asset management API
- skills: skill extraction API
- CLI API blueprint: DifyCli callback endpoints (/cli/api/*)

Dependencies extracted (64 files, ~8000 lines):
- models/sandbox.py, models/app_asset.py: DB models
- core/zip_sandbox/: zip-based sandbox execution
- core/session/: CLI API session management
- core/memory/: base memory + node token buffer
- core/helper/creators.py: helper utilities
- core/llm_generator/: context models, output models, utils
- core/workflow/nodes/command/: command node type
- core/workflow/nodes/file_upload/: file upload node type
- core/app/entities/: app_asset_entities, app_bundle_entities, llm_generation_entities
- services/: asset_content, skill, workflow_collaboration, workflow_comment
- controllers/console/app/error.py: AppAsset error classes
- core/tools/utils/system_encryption.py

Import fixes:
- dify_graph.enums -> graphon.enums in skill_service.py
- get_signed_file_url_for_plugin -> get_signed_file_url in cli_api.py

All 5 controllers verified: import OK, Flask starts successfully.
46 existing tests still pass.

96641a93f6 feat(api): add Agent V2 node and new Agent app type (Phase 1-3) 
Introduce a new unified Agent V2 workflow node that combines LLM capabilities
with agent tool-calling loops, along with a new AppMode.AGENT for standalone
agent apps backed by single-node workflows.

Phase 1 — Agent Patterns:
- Add core/agent/patterns/ module (AgentPattern, FunctionCallStrategy,
  ReActStrategy, StrategyFactory) ported from feat/support-agent-sandbox
- Add ExecutionContext, AgentLog, AgentResult entities
- Add Tool.to_prompt_message_tool() for LLM-consumable tool conversion

Phase 2 — Agent V2 Workflow Node:
- Add core/workflow/nodes/agent_v2/ (AgentV2Node, AgentV2NodeData,
  AgentV2ToolManager, AgentV2EventAdapter)
- Register agent-v2 node type in DifyNodeFactory
- No-tools path: single LLM call (LLM Node equivalent)
- Tools path: FC/ReAct loop via StrategyFactory

Phase 3 — Agent App Type:
- Add AppMode.AGENT to model enum
- Add WorkflowGraphFactory for auto-generating start->agent_v2->answer graphs
- AppService.create_app() creates workflow draft for AGENT mode
- AppGenerateService.generate() routes AGENT to AdvancedChatAppGenerator
- Console API and DSL import/export support AGENT mode
- Default app template for AGENT mode

Old agent/agent-chat/LLM node paths are fully preserved.
38 unit tests all passing.
