fix(why): drop inaccurate Slack vs GTA V comparison (#28)

* fix(why): drop inaccurate Slack vs GTA V comparison

GTA V's install size (~95 GB) dwarfs Slack's (~400 MB) by orders of
magnitude, so the original line was factually wrong. Replace with an
accurate Chromium-duplication line that keeps the rhetorical punch.

* fix(why): correct PWA disk footprint in scoreboard

Service-worker caches for typical PWAs (Twitter ~50 MB, Spotify Web
~100 MB, productivity apps 50–100 MB) hold far more than ~1 MB. The
table now reflects a realistic 5–50 MB range.

* revert(why): restore PWA ~1 MB cache disk figure

Per maintainer: disk figures across the scoreboard explicitly exclude
icon weight, so the original "~ 1 MB cache" was correct as the bare
service-worker / app-shell footprint.
