Debug: fix headless mode, plugin compat, psutil optional, module imports

- headless: TUI skip now works correctly
- example_plugin: keyword args compat (plugin_name=, config=, bridge=)
- sysmon: psutil made optional (graceful degrade)
- tui_service: SysMonWidget optional
- All 22 modules import clean, 23 tests pass, integration verified
