feat: expand local operator controls across CLI and WebUI

- Add structured CLI commands for status/kernel/settings/plugins/memory/knowledge/agents
- Inject core dependencies directly into CLI plugin for non-HTTP operator workflows
- Add plugin management panel and API proxy endpoints to WebUI
- Let cmd_run inherit default workdir from core.agent.workdir
- Use fixed loopback address for pluginmgr API
- Remove stale MaxToolTurns config usage from homed wiring
