docs(plan): defer in-game chat, add Phase 1 (Casual) implementation plan

- DECISIONS.md: in-game chat (player↔player and human↔Gemma) deferred
  indefinitely. Blind-mode chat is a side channel that defeats the
  moderator-vocabulary security boundary; chat with Gemma leaks belief
  state mid-game. Resolvable but expensive — revisit only on demand.
- Spec: same deferral noted in "Out of scope".
- New plan: docs/superpowers/plans/2026-04-28-ai-player-phase-1-casual.md
  — 13 tasks, 80 sub-steps. Phase 1 only (Casual bot end-to-end). Phase 2
  (Recon) gets its own plan once Phase 1 outcomes inform Recon's target.

- In-game chat (player ↔ player or human ↔ Gemma). Considered 2026-04-28; deferred indefinitely. Player chat in blind mode is a side channel that bypasses the moderator-vocabulary security boundary; chat with Gemma leaks the bot's belief state and undermines the post-game reasoning reveal. See `DECISIONS.md` "Deferred / Rejected" for the full rationale.
