Prevent display sleep by default

Browse Source 
`caffeinate -i` blocks system idle sleep but lets the display blank, so the
screen still slept and the extension looked broken. The "Also Prevent Display
Sleep" preference that fixes this defaulted to off.

Flip it to on, and guard it with a manifest test that reads package.json and
asserts the shipped defaults map to `-i -d`. Verified on macOS: `caffeinate -i`
yields PreventUserIdleDisplaySleep 0, `caffeinate -i -d` yields 1.
