New nodes (5):
- Relay: local message delivery between agents (outbox→inbox)
- ChatHistory: multi-turn conversation persistence across runs
- PromptTemplate: {a}/{b}/{c}/{d} variable substitution
- ConditionalRouter: keyword/regex routing with matched/unmatched outputs
- BatchSplitter: split text into numbered sections by delimiter
Fixed nodes (3):
- TextCombine: removed forceInput, text_a/text_b now typeable widgets
- Remember: removed forceInput on text, now typeable widget
- Send: removed forceInput on body, now typeable widget
Demo workflows (7):
1. Character Design - art director with memory for consistent characters
2. Novel Crafter - writer+editor dual-agent with Relay message delivery
3. Story to Video - director breaks story into scenes with BatchSplitter
4. Multi-Turn Chat - persistent conversation history across queue runs
5. Agent Debate - two agents argue via message passing (FOR vs AGAINST)
6. World Builder - game world with PromptTemplate for locations/characters
7. RAG Pipeline - store docs, search, answer with ConditionalRouter error handling
76 tests all passing (46 original + 30 new).
