Don't launch from the hero's Install, and check page names with V8

From the independent review of this PR:

- After installing the featured app, the hero's Install on the Frame took the
  installed branch and launched it on the headset. It now opens the details,
  whose button says Open in Steam, without acting.
- The duplicate-name test matched declarations at column zero only, so an
  indented second loadPanels (the bug it was written for) passed, and so did
  classes, destructuring and later declarators. It now compiles both inline
  scripts as one strict-mode block, where V8 rejects any name declared twice
  in the shared scope, with fixtures for each case and for same-named helpers
  in different functions (which are fine).
- A card's "Won't run" overstated the check's "Might not work"; it now says
  May not run.
- Removed styles and the source-filter state that nothing used any more.
