- adds an UNUSABLE_TERMINATOR route error code and UnusableTerminatorError for a terminator the router
still has registered but can't dial
- reports an edge terminator that is being removed, or whose SDK channel has closed, as unusable
before opening a connection on it, instead of failing in the msg mux with a generic error
- dials the replacement when a new bind takes over an edge terminator while the dialer is looking it up
- doesn't take over an edge terminator the dialer would report unusable, and orders the takeover with
the dialer's recheck, so an id reported unusable isn't reused
- reports an ER/T terminator that is closing or being removed as unusable
- skips terminators reported invalid or unusable in path selection for up to a minute, and clears
the mark when the terminator is created, deleted, or re-established by a create for an existing id
- keeps deleting terminators reported invalid, and logs the delete failure that was dropped before
- adds the ROUTER_ERR_UNUSABLE_TERMINATOR circuit failure cause
- passes a RouteSenderEnv to the route sender in place of its separate dependencies
