fix: remove "5 min to midnight" banner from doomsday strip

[Copilot]

The "X.X MIN TO MIDNIGHT" text in the doomsday strip was confusing without adding meaningful information — the clock hand and progress bar already convey proximity to the threshold visually.

Changes

• index.html — Removed the #doomTimeText element from the doomsday strip
• src/js/18-scary-features.js — Removed the minsLeft calculation and doomTimeText update block from updateDoomsdayClock()
• styles/scary-features.css — Removed the now-orphaned .doomsday-time rule

Summary by CodeRabbit

• User Interface
  • Simplified the Doomsday Clock display to show only the percentage indicator, removing the "MIN TO MIDNIGHT" countdown text.

📝 Walkthrough

Walkthrough

Sucka! This PR removes the Doomsday Clock time display feature by eliminating the HTML time text element, the JavaScript calculations and DOM updates that populated it, and the associated CSS styling class. I pity the fool who doesn't track this removal!

Changes

Cohort / File(s)	Summary
Doomsday Clock Time Display Removal index.html, src/js/18-scary-features.js, styles/scary-features.css	Removes the time-to-midnight display component entirely: deletes the #doomTimeText HTML node, strips out the minsLeft calculation and DOM update logic from updateDoomsdayClock(), and eliminates the .doomsday-time CSS styling block. Fool, the percentage subtext display remains intact!
