Add comprehensive unit tests for CLIProxy proxy lifecycle:
- Status command logic: session lock exists/not, uptime formatting
- Stop command logic: stale lock cleanup, active proxy stop
- Command routing: stop/status subcommands, unknown handling
Tests cover the CLI handlers for the new proxy persistence feature.
