feat: add dynamic Office mode for agent families

[Adayhg]

Summary

• Add a dynamic Office view with Sims-like avatars, rooms, states, and a reversible Graph switch.
• Discover new Codex agents from live rollout families, preserve root-to-child and nested relationships, and use stable opaque IDs with fail-closed handling for unknown or ambiguous targets.
• Keep Office projection sanitized; telemetry is opt-in and local services bind to localhost.

Validation

• npm test: 83 passed, 0 failed (root 33, web 10, extension 40).
• TypeScript checks passed for web, extension production, and extension tests.
• Next production build, Vite webview build, and extension build passed.
• Live canary observed one family with a root placeholder, two direct children, and one nested grandchild; 4 agent_spawn events were grouped into one session.
• Rollout files remained unchanged while watched; UI and relay listened only on 127.0.0.1.

Follow-up activation gates

• Run the full 30-minute canary, measure end-to-end discovery latency, and verify atomic rename/replacement rotation before treating this MVP as production-activated.

Follow-up: work-based agent names

Agents now receive a fixed-vocabulary Spanish role label inferred from bounded work hints:
Orquestador, Seguridad, Validador, Investigador, Implementador, Documentador, Diseñador,
Integrador, Analista, or Especialista. Terra/Luna are shown as a secondary model-family
marker (for example, Seguridad · Terra). The original prompt/task text is never copied
into the label, and the opaque ID remains available for exact identification.

Validation after this follow-up: 86 tests passed; TypeScript, Next, webview, and extension
builds passed.
