- Hang fix: 120s timeout on compression LLM call + raw_stream
channel-close handling (None => break instead of spinning)
- Supervisor effective active count: stop counting finished
JoinHandles as occupying capacity slots
- Universal tool result size cap: truncate_if_needed() on
ToolResult, applied in eval_tool_calls() after escalation block;
configurable via max_tool_result_chars in AppConfig/AgentConfig
- Windowed compression: compression_keep_last config param keeps
the N most recent messages visible after compression
- Fix pre-existing flaky test: add #[serial] to
handle_list_available_unrestricted_when_no_whitelist so it does
not race with TestConfigDirGuard-based tests that temporarily
populate the agents data dir
