Drop pi-intercom and move oracle/reviewer to Opus 4.8

[boga]

Why

Subagents hung indefinitely whenever one called contact_supervisor during a
chain or parallel run. That tool is a blocking intercom ask: the child freezes
waiting for a reply the parent can never send (the parent is itself blocked
inside the subagent() call, or the ask lands in an exited coordinator
session). There is no timeout, so the hang is permanent.

Rather than restrict each agent's toolset, this removes the source: dropping
the pi-intercom extension removes the contact_supervisor/intercom tools
entirely, so no agent can issue a blocking ask.

Separately, oracle and reviewer are promoted to a stronger reasoning model.

What

• Drop npm:pi-intercom from pi_agent_settings_packages (group_vars/all.yml).
  Removes contact_supervisor globally — fixes the hang at the root.
• oracle + reviewer → anthropic/claude-opus-4-8, thinking high
  on both hosts:
  • work: was google/gemini-3.1-pro-preview.
  • home: was openai-codex/gpt-5.5; also added anthropic/claude-opus-4-8
    to enabledModels so the override resolves there.

Notes

• User-scoped config; no project files affected.
• Takes effect after applying the playbook
  (ansible-playbook site.yml --limit <host> --tags configs). The settings
  merge is recursive/additive — re-running drops pi-intercom from the
  generated settings.json packages list.
• The plan's optional tools: allowlists were intentionally skipped; dropping
  the extension makes them redundant.

Poem

🐇 A package removed, a model switched anew,
From Gemini's glow to Claude's deeper hue,
The oracle speaks in Anthropic's voice,
The reviewer too — a deliberate choice.
Hop, hop, configs tidy and true! ✨
