fix(theseus/chrome): self-heal chrome-view height drift every 750ms

Browse source 
The onTabs / onNav re-sync catches the common menu-close path, but a menu
that gets orphaned by a drag interruption, a focus flip, or a submenu
race can leave the chrome view taller than the natural body-scrollHeight
until the next tabs/nav event fires. Symptom: a huge blank strip between
the address bar and the page that grows and doesn't shrink until the tab
changes.

Fix: a 750ms interval that re-runs syncHeight whenever no .ctxmenu /
.grouppop is present. setChromeHeight in main.js only re-layouts when
the value actually changes, so this is a cheap no-op in the steady state.

Holding the ship: will bundle with the next batch per the slower-cadence
policy. Users on 0.3.5 keep the existing gap fix; this one lands with
the next release.
