- SystemPipeline: Entry point for console/webhook/API messages
- TextInput/TextOutput: Generic primitives for human text I/O
- Server: WebSocket "send" command routes through SystemPipeline
- Console: @target message now injects into pipeline
Flow: Console → WebSocket → SystemPipeline → XML envelope → pump

Implements an observer pattern where agents can register watchers
for conditions on their thread. When the condition is met, the
agent gets "nagged" on subsequent invocations until it explicitly
closes the todo.
Key components:
- TodoRegistry: thread-scoped watcher tracking with eyebrow state
- TodoUntil/TodoComplete payloads and system handlers
- HandlerMetadata.todo_nudge for delivering raised eyebrow notices
- Integration in StreamPump dispatch to check and nudge
Greeter now demonstrates the pattern:
1. Registers watcher for ShoutedResponse from shouter
2. On next invocation, sees nudge and closes completed todos
3. Includes nudge in LLM prompt for awareness
