Add Week 2 depth systems: research, events, competitors, talent, data

Tech tree with 21 research nodes across 5 categories (infrastructure,
efficiency, generation, specialization, safety). Research page with
category-grouped cards, progress tracking, prerequisite gating.

Event engine with 34 events across industry/regulatory/PR/internal/market
categories, weighted random firing, cooldowns, expiry, and choice modal
with consequence preview. Events auto-expire with default choice.

Competitor system with 3 rival AI labs (Prometheus AI, Nexus Labs, Titan
Computing), personality-driven milestone progression, and comparison UI.

Talent page with department hiring, headcount management, and key hire
recruitment from a pool of 10 named characters with special abilities.

Data marketplace with 8 purchasable datasets, user data flywheel from
subscribers, and data system processing in tick loop.

Era transition system checks revenue/capability/reputation thresholds.
All new systems integrated into tick processor with notifications.
