Slash commands can announce a default effort level via a notice

Slash commands can tell you which effort level they defaulted to when you didn't specify one.

What

Command dispatch gained two optional hooks, onUserTypedArgs for interactive invocations and getDefaultEffort, whose returned .notice is rendered as a notice message when the user did not type an effort explicitly.

Details
  • effort resolution order for a command is now getEffort ?? getDefaultEffort()?.value ?? effort
  • onUserTypedArgs fires only for interactive invocations, not programmatic dispatch
  • the notice is shown only when no explicit effort was typed, so a user-supplied effort stays silent
Evidence

let k = g.getDefaultEffort?.(A, n)?.notice;

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
