feat(huh prompter): add placeholder to search input

BagToad · Copilot · williammartin · commit f38abbe1ca5c · 2026-03-26T14:26:17.000+01:00
Add 'Type to search, Ctrl+U to clear' placeholder to the
MultiSelectWithSearch search input. Set WithWidth(80) in the test
harness to prevent textinput placeholder rendering panics when
there is no terminal.
