Refresh planner queue after input resume

[asim]

Summary

• Drop the closed input-required CLI continuation item (Add CLI continuation for input-required agent runs #4755/Add CLI input resume for agent runs #4758).
• Add Stream remote agent replies through micro chat #4760 as the next builder item: stream registered-agent replies through micro chat --stream with fallback and inspectable history.

Testing

• go build ./...
• timeout 120s go test ./... (environment/provider and loopback failures; command timed out after partial run)
• golangci-lint run ./... (local binary built with Go 1.24, module targets Go 1.25.12)

Closes #4759
