Summary
Remove Runlet-specific observation and stderr progress tracking now that nested tool calls use canonical ACP lifecycle notifications. This is the second PR in the stack, based on #215.
Motivation
Source-node matching and duplicate child lifecycle events are no longer needed to display nested compose activity. Removing them leaves ACP as the source of tool-call identity, content, and status.
Impact
The TUI retains grouped child calls and a bounded, neutral source view, without binding, loop, or retry-state annotations. General stderr diagnostics continue to carry session attachment, storage, compaction, subagent lifecycle, usage, activity, and cleanup information.
Technical details
The runtime delegates directly to
RunletBackend.execute. Both observed-tool invocation paths retain canonical ACP projection.The general diagnostic writer moves to its own module, preserving bounded publication, loss invalidation, heartbeat fairness, and leases. Its existing
runlet_transporthealth tag remains unchanged. ACP capacity and terminal-display limits no longer depend on the removed progress model.
