Subject: [PATCH] fix(desktop): keep /resume's free-text search typeable
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

/resume was classified as an options command, but its argument is a
free-text query the picker fuzzy-matches against session titles and
previews. Its completion list also always ends in a "Browse all
sessions…" action row, so Space-to-accept never fell through to an
empty list: the first space in a multi-word query emptied the composer
and threw the user into the overlay, query and all.

Classify it as mixed so spaces type through, matches keep narrowing as
you refine, and Tab or arrow-then-Enter still accept a highlighted
session.
