Docs: LANTERN Phase 0 — full pivot adoption + all-doc sweep

Adopt LANTERN as the operative direction (co-op action-RPG, light-as-territory),
superseding the Awakening Engine fiction + the Co-op Hades iteration. Existing
code becomes salvage quarry; the mechanical pillars hold.

Phase 0 deliverables (doc portions):
- DR-048 adoption decision record (0.1)
- Lantern_Strip_Mothball_Inventory — system-by-system keep/rework/mothball (0.2)
- Lantern_World_Model_Spike — pocket-graph + seed-pinning BRIEF, review-first (0.3)
- Art_Direction_Lantern — style bible + material decision + A0 gate (0.4)

Docs/skills sweep: Pillars pointers + LANTERN locked decisions; superseded
banners on Identity, Iteration_CoopHades, Path_to_Fun, Milestones, Backlog,
End_Of_Month (all redirect to the LANTERN roadmap); Home MoC + current-direction
callout (and stale serena line fixed); Systems_Index era note; CLAUDE.md
core-loop line -> LANTERN direction pointer (verbose co-op-Hades invariants
archived to the gotchas archive, net-neutral under the 40 KB budget); dots-dev
validation-harness expedition-run recipe flagged era-specific.

Two Phase-0 gate items remain OPEN (not doc work): the 0.3 world-model design
review and the 0.4 in-engine style-proof scene.
