Folder repos refuse silent in-place runs

A Folder repo ticket that names no child repo is now refused instead of quietly running at the folder root. A commit probe proves a run can land its work before any agent spends money.

Added

A Folder repo ticket that names no child is refused and marked undeclared, and the ticket form offers a child picker
QA on a Folder repo follows the child repo the slice actually touched
trau doctor makes a trial commit, and a run that could not commit pauses with a named remedy before any agent starts
Interview attachments accept any file type, shown as a file chip in the transcript and on the ticket
Lane database copies work without the database client installed by using the database’s own Docker container

Fixed

An epic waiting its turn no longer raises a misleading “Spawn held” warning
