Remove events system entirely

The random events (GPU shortages, regulatory hearings, PR crises, etc.)
added interruption without enough gameplay value. Removed all event
types, definitions (~1800 lines of event data), the event processor,
EventModal UI, store actions, and tick integration. Updated docs to
reflect the removal. Bundle size drops ~47kB.

 - **Timing funding rounds matters.** Raise too early and you give up equity cheaply. Raise too late and you run out of runway.
 - **Safety research compounds.** Each safety project improves all future models.
 - **Check competitor activity.** If a rival just released a strong model, expect to lose some subscribers unless you respond.
