🤖 Spire 0.2.2: drop superpowers default, build settings, pinned role agents

- Superpowers is no longer part of the cycle; it survives only in
  implementation/references/superpowers.md (older models, override table).
- implementation: plan altitude, staleness check in the attack, phase
  review records unplanned work (never auto-reverts).
- Igor: orienting is not deciding, light grilling trial in brainstorm,
  research briefs ask for findings, journal times from `date`.
- project/init: `## Build` settings section, gitignored project.local.md
  override.
- New pinned agents planner, attacker, reviewer (Opus 5.5).
- .codex/config.toml mirrors .claude/settings.json (spire + gitea).
