feat: Dynamic identity system prompt from bot config

- Build system prompt dynamically using bot.name and bot.owner from config
- Reorder prompt: identity -> static prompt -> MeshMonitor (conditional) -> mesh context
- MeshMonitor description only injected when meshmonitor.enabled is true
- Update default system_prompt to static parts only (commands, architecture, rules)
- Fix meshmonitor.py to handle trigger arrays (not just strings)
