v0.3.0

Compact legacy-style terminal panel: service list, full-width separators, selected live logs, keyboard controls and version footer. F2 selects next service; F3 start/stop; F4 restart; Ctrl+L clears only the view; quitting leaves services running. Preserves prompt via --prompt. Linux validation: 32 tests passed, one Windows-native test skipped, installed-package and PTY checks passed. Windows remains experimental.
