QA reports on the ticket and exportable research

Trau writes its QA findings back onto the ticket, research becomes a document you can approve and export, and a failed run can go straight to an interview that proposes the fix.

Added

An optional QA report comment on the ticket lists what trau checked and found, with screenshots, on Linear, Jira, Azure DevOps and GitHub
Hand a failed run to the Inbox in one click; the interview already knows what went wrong and requeues the ticket when you accept
Research reports are documents with a title and sources, exportable as Markdown or PDF, and a run waits for plan approval first
Every agent at work is visible from anywhere in the app, with the repo switcher and sidebar marking what is running
trau hub start starts the hub from the command line

Changed

Search ranks an exact or prefix ticket id match first and pushes finished work down
