Teammate mode-change message type removed from the schema

Teammates can no longer even send a permission-mode change message; the shape was dropped from the schema.

What

The message shape teammates used to request a permission-mode change, carrying a mode and a sender, was deleted from the set of messages agents can exchange, so such a message can no longer be parsed at all.

Evidence

mode_set_request

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