Session auto-restart with project context persistence

Summary

When running multiple Claude Code agents as domain teams on a long-running project, sessions eventually hit context limits or need refreshing. Currently the operator must manually restart each agent. All the context needed for a fresh session to pick up where the last left off already exists on disk (project instructions, handover docs, work queues), but there's no way to trigger "end this session, start a new one automatically."

Use Case

• Multi-agent architecture where 4-5 Claude Code desktop sessions run as independent domain teams
• Each agent reads CLAUDE.md + a work queue API + handover docs on startup to know what to do
• Sessions degrade over time (context window fills, stale state accumulates)
• Operator wants agents to self-refresh: end session, immediately start a new one that reads the same project context and continues working

Proposed Behavior

A configuration option (in settings.json or .claude/config) that enables auto-restart:

• When a session ends (context limit, explicit /exit, or idle timeout), automatically start a new session in the same project directory
• The new session reads CLAUDE.md and any startup instructions as normal
• Optional: a startup prompt file (e.g., .claude/startup.md) that the new session executes automatically

Why This Matters

The persistence layer already exists — CLAUDE.md, memory files, handover docs, work queues. The only missing piece is the trigger to start a fresh session that reads them. Without it, the operator becomes a manual restart button for N agents.
