Bug Fixes

• Fixed effect queue race condition where multiple approval prompts could display simultaneously when using sub-agents
• Fixed ESH template processing to run from working directory instead of SYSTEM.md location

• Updated system prompt with complete tool list
• Removed confusing "You (pending)" header from staged approval blocks
• Removed redundant background parameter from spawn_agent tool schema
• Suppressed false-positive dead_code warnings from dual lib/bin compilation
• Added 22 new tests for Stage and EffectQueue concurrency
