Claude Haiku 5.5 now default, with subagent type tracking and tool registration improvements

Added

• Added Claude Haiku 5.5 (claude-haiku-5-5), now the default Haiku model on the Anthropic API — 1M context, $0.10/$0.50 per Mtok ($0.50/$2.50 for prompts over 100K)
• Added agentType to the subagentStatusLine payload, so scripts can tell custom subagent types apart
• Added isDeferred to $.tool.register for mods: false lists the tool's schema in the prompt from the start instead of behind tool search

Changed

• Reverted the auto mode denial message change from 2.1.281 that told Claude a denial covers the outcome, not only the exact command
• Reverted the 2.1.290 fix for cloud sessions staying asleep after a container restart lost a pending /loop wakeup or scheduled task; Claude is no longer told, and the session stays asleep
• Changed claude.ai skill syncing to check for changes about every 40 minutes, instead of every 10, while no session is in use
• Changed the order of agent lists and of MCP servers announced to the model: names with non-ASCII characters now sort after ASCII names
• Changed OpenTelemetry claude_code.at_mention logging to emit at most 100 agent and 100 MCP-resource events each time a prompt is read
• Self-hosted runner: Changed the orchestrator to sleep 4 to 6 seconds between polls instead of a constant 5, so several replicas for one environment stop polling at the same moment
• [Claude Tag] Changed Claude in Slack to join announcement channels, where only admins can post, without posting its intro
• [Claude Tag] Changed the limit on channel rules in Claude Tag admin settings from 20 to 50 for each workspace and for the organization-wide Slack page
