Docs: redirect to co-op roguelite — Expedition spine + classes + persistent meta

Playtest of the single-arena slice (Scratch Notes 6152026) found it stale fast.
Answer the post-END-2 Decision Gate as continue/expand: re-scope off the fixed
June-30 demo to a co-op roguelite-ARPG — base = persistent buildable hub (never
resets), the procedural Expedition region = the required combat spine, two classes
(Warrior/Ranger), persistent meta (SaveData v6 later). Mission-as-Sortie model:
fulfils locked pillar #4, preserves the never-a-run-reset pillar; reverses DR-031's
expedition pause. Backed by an 8-agent design+feasibility pass (feasibility GREEN:
server-spawns-ghosts removes seed replication). Slice doc archived/superseded.

See DR-037.
