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.
