wayfinder: remove the Handoff ceremony

Every session ended with a Handoff that queried the frontier and emitted
per-ticket copy-paste commands — real token cost each session. Cut it
entirely and let the natural flow carry continuation: the next
/wayfinder session already loads the map and picks the next frontier
ticket, so nothing is lost, just deferred to re-invocation.

Reconciles the references left behind: the one-ticket-per-session rule
and "charting is one session's work" constraint survive as plain lines;
the Refer-by-name paragraph drops its Handoff mentions.

The id and URL don't vanish — a name wraps its link, and Handoff commands still paste the URL — but they ride *inside* the name, never stand in for it.

-**No open tickets remain.** The fog is pushed back far enough that the way to the goal is clear — the map is done. (The initial grilling may also surface no fog at all, in which case there was never a map to chart.) Recommend implementing directly, or using `/to-prd` to schedule a multi-session implementation.
