With discord-dm gone the verb set, listCommandRecords filter, resolveBridgeVerb
throw and the verb variable decided nothing, and the filter hid non-discord-post
commands so they stayed pending with no receipt. Delete all of it: a command
whose verb is not discord-post now reaches processOneCommand and is refused
with a failed receipt (error names no input value). Payload staging moves
inside the try so a refusal cannot escape as a thrown error.
Adds tests/cultmesh-bridge-commands.test.mjs: discord-dm refused with failed
receipt and non-ok result, canary-free error, discord-post still reaches the
actuator.
