agents: give the merge-state commands their pass conditions, and run them as written

Browse Source 
sylpheed-port's standard, applied here: a documented command nobody has executed is
the same class as a control that does not execute. Mine did execute, but they were
published without expected outputs, and a command with no pass condition is half a
check -- a reader gets a number and no way to know whether it is the right one.

Each command now carries its pass condition, the placeholders are real shell
variables rather than <branch>, and the last run's results are recorded: 330, exit
0, 0, 1.

⚠️ **All four were run as written before this was published**, and the expected
result is stated beside each — a documented command nobody has executed is the same
class as a control that does not execute, and a command without a pass condition is
half a check. Last run 2026-08-31: `330`, exit `0`, `0`, `1`.
