The C code picks a starting player via dice roll but doesn't reorder
the player array. The parser now tracks _first_player_idx and rotates
the players list in get_state() so the UI shows them in actual turn
order.
The root cause: checkpoint handler queued .trade via say_delayed, but
monop sends '-- Command:' before processing the trade. The old handler
reset in_trade and queued .roll, so both commands got sent.
Fix: checkpoint handler no longer sends commands. The -- Command:
prompt is where the bot decides to trade or roll, matching how monop
actually works (-- Command: is the interactive prompt).
Also: no trades while in jail (jail has no -- Command: before roll).
Updated all tests to reflect the new flow.
- Handle 'Which player do you wish to trade with?' prompt when
in_trade is True (was silently returning, causing bot to roll
during an active trade prompt)
- Simplify property trade offers to always say 'done' (cash-only
trades) to avoid getting stuck on property list prompts
