feat(wayfinder): run research inline as a subagent, not as a ticket

Research is fully AFK and yields a fact, not a decision, so it never
earns a ticket's session boundary. Drop `research` from the
`wayfinder:<type>` set and reframe it as inline fuel: any session
spins up a `/research` subagent the moment it hits a knowledge gap,
captures the findings on a throwaway `research/<name>` branch, and
leaves a context pointer on the ticket it informs (or the map's Notes).

Updates the SKILL, the GitHub/GitLab/local tracker type lists, and the
docs page, plus a changeset.

 Beyond the live tickets lies the **fog of war** — decisions you can tell are coming but can't yet pin down. The test for whether something is a ticket or still fog is whether you can *state the question precisely now*, not whether you can answer it. Resolving a ticket clears the fog ahead of it, **graduating** whatever's now specifiable into fresh tickets. The **frontier** is the open, unblocked, unclaimed tickets — the edge of the known — and it's what the tracker's native blocking renders visually, so you see what's takeable without opening the map. Fog only gathers *toward* the **destination**; work past it is ruled **out of scope**, closed, never graduating.
 
-Every ticket is **HITL** (human in the loop — grilling, prototype) or **AFK** (agent alone — research); a HITL ticket only resolves through a live exchange, so the agent never answers its own questions.

-`wayfinder` is a big-idea **on-ramp**: an effort too large and foggy to spec in one sitting generates a cleared map of decisions, which then merges onto the main build flow. When the fog is pushed back and the way is clear, hand off to [to-spec](https://aihero.dev/skills-to-spec) to schedule the multi-session build (or, if the effort turned out small, implement directly). It leans on [grilling](https://aihero.dev/skills-grilling) and [domain-modeling](https://aihero.dev/skills-domain-modeling) to resolve individual tickets, and on [prototype](https://aihero.dev/skills-prototype) and [research](https://aihero.dev/skills-research) for the ticket types that need them.
