"""Tests for the bot CLI (app.bot_cli).

The CLI mirrors the Telegram bot's manual-trigger surface (Telegram
handlers /1, /2, /3) plus the operational ops (credit, transfer,
monitor-once). With no args, it drops into a stdlib TUI menu.

These tests mock app.bot_cli.CM_BOT_HAL so they never touch the database
or cm99.net. The HAL class is imported at module load (which is a pure
import — no env reads), so we can patch the symbol bound on app.bot_cli
without affecting other tests.
