wayfinder: use placeholders in Handoff example, drop no-op

Cut the "(trailing name orients you; it's ignored on paste)" gloss —
a # comment is self-evident. Replace the arbitrary "Briefing pipeline"
map name and specific ticket names with <map name>/<ticket name>
placeholders, consistent with the surrounding <map-url>/<issue-url>
style so nothing reads as a real referent.

+Make **`wayfinder`**'s no-duplication contract explicit: the map is an **index**, not a store.
+
+Adopting "index" as the leading word for the map's role fixes two duplication risks. The map now states up front that a decision lives in exactly one place — its ticket — so it only ever gists and links, never restates the answer (previously this rule was implied inside an HTML comment in the map-body template). And graduating fog into a ticket now clears the graduated patch from the Fog, so a suspected question can't linger in both places at once.

 description: Chart a route through a foggy problem — turn a loose idea into a shared map of investigation tickets on your issue tracker, and resolve them one at a time until the way to the goal is clear.
-disable-model-invocation: true

 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, the Handoff — 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, and Handoff commands still paste the URL — but they ride *inside* the name, never stand in for it.

 ## The Map
 
 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.

+The map is an **index**, not a store. It lists the decisions made and points at the tickets that hold their detail; a decision lives in exactly one place — its ticket — so the map never restates it, only gists it and links.

 **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.
