Bug type

Regression (worked before, now fails)

Summary

When typing /acp close (or any action inline), Discord sends the interaction with action = null because the field uses static choices — so OpenClaw always falls back to the button picker menu.

Root cause: buildDiscordCommandOptions registers the action arg with static choices (17 options, under Discord's 25 limit), which forces Discord's dropdown UI. Users can't bypass it by typing inline.

Fix: Register action with autocomplete: true instead of static choices. This lets users type freely, Discord passes the value through, and resolveCommandArgMenu correctly skips the menu when a value is present.
Cant just type /acp close in discord, it still shows the selection menu instead of bypassing it straight to closing the acp sub agent
