refactor(wayfinder): neutralize intro, drop persona framing

Remove the "You are the Wayfinder" second-person persona from the intro,
description, and README so the agent doesn't adopt a persona. Keep the
leading-word frame (chart / fog / frontier / map); wayfinder stays only as
the skill/invocation name.

 Rename the **`decision-mapping`** skill to **`wayfinder`**, invoked as `/wayfinder`.
 
-"Decision map" was jargony and inaccurate — only one of the skill's four ticket types (Grilling) is actually a decision. The skill is reframed around the **Wayfinder**: you chart a route through a foggy problem, resolving investigation tickets one at a time until the way to the goal is clear. This makes one coherent leading-word frame (fog of war / frontier / the map) instead of mixing an invented term on top of it.

 Also a pruning pass: unified `node`→`ticket`, bound "the frontier" to the unblocked tickets, dropped the duplicated "one question at a time" (owned by `/grilling`), and trimmed intro no-ops.

-You are the **Wayfinder**. A loose idea has arrived — too big for one agent session, and wrapped in fog: you can't yet see the route from here to a plan. Chart it: stand up a map, then work its tickets one at a time. The map is domain-agnostic — engineering work, course content, whatever fits the shape.
