* check if any incoming message is from a channel with a pending
  recycle request
* if so, redeem it (and notify admins/maintainers) right away!

side-effect:

* refactor dispatcher.dispatch to extract handling of early-returning
  and non-early returning side-efffects just before `relay`
  * tuck all logic that detects actionable state from system messages
    and possibly returns early after processing it into a
    `detectInterventions` helper (which returns an `intervetnion` func
    and returns early after calling it)
  * tuck all logic that detects and takes action but does not require
    returning early into a `detectSideEffects` function, which returns
    an array of side-effects to perform before proceeding to `relay`
