Two managed browser harnesses

Browser verification now runs on two harnesses trau installs itself, with automatic fallback. The installer puts trau in a directory you own, so updates need no administrator.

Added

Trau installs two browser harnesses itself and falls back to the second when the first fails to start
Hub → Browser runtime shows what is ready and the one command to copy for anything the machine still lacks
An Inbox interview accepts extra context while a round of questions is open and keeps the answers you gave
Finished tickets on the Loop page link to their run details

Changed

The installer puts trau in a directory you own and never runs sudo, so trau update works without an administrator

Fixed

No browser session outlives its run, and an app URL that never answers is reported before verify starts
