Design's command switcher exposes Open tabs / History / Bookmarks /
Actions. The implementation now includes a Bookmarks section sourced
from snapshot.bookmarks: filtered by lowercase needle on title and
URL, capped at RESULT_LIMIT, rendered with brand glyphs, opening the
URL on click.
Match helpers (matching_tabs / matching_history / matching_bookmarks)
move into chrome::command_match so command_overlay.rs stays under the
500-line ceiling. Ask ELY remains skipped — no AI surface in domain
yet, no fabrication.
