A sort key can now name a header or query parameter column (`field:header.x-cache`). The
database sorts it by the value the column shows, read from the stored headers or URL with the
name bound as a parameter, and the app's in-memory sort places live flows the same way. Custom
column headers sort on click and Option-click and their menus' sort items work; the sort is
kept with the columns and removing a column drops it from the sort.
The Add Column field completes `@` and the paths a column accepts, with no colon and no values,
opens its menu on focus, normalises a pasted term, and says why a path cannot be added.
