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.

 A loose idea has arrived — too big for one agent session, and wrapped in fog: the route from here to a plan isn't visible yet. This skill charts it as a **shared map** on the repo's issue tracker, then works its tickets one at a time. The map is domain-agnostic — engineering work, course content, whatever fits the shape.
 
+## Refer by name

+Every map and ticket is an issue, so it has a **name** — its title. In everything the human reads — narration, the map's Decisions-so-far — refer to it by that name, never by a bare id, number, or slug. A wall of `#42, #43, #44` is illegible; names read at a glance. The id and URL don't vanish — a name wraps its link — but they ride *inside* the name, never stand in for it.

 The map is a single issue on this repo's issue tracker, labelled `wayfinder:map` — the canonical artifact. Its tickets are child issues of the map.

-**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.
