TUI: model picker traps session after typing in search field

Description

Opening the model picker with /models works, but typing anything in the search field empties the list and traps the picker: esc, enter, arrows, q, ctrl+c do nothing. Printable keys still land in the search field. Clearing the query with backspace does not bring the list back, so the only way out is to kill the process. With nothing typed, esc closes the picker normally, and the same flow works in 1.18.29 — looks like a v2 regression in the filtering path. Silent failure: nothing on stderr, nothing in the debug server log.

Plugins

none (empty config)

OpenCode version

Steps to reproduce

1. echo '{}' > /tmp/oc.json && OPENCODE_CONFIG=/tmp/oc.json opencode --standalone
2. Run /models, type one character in the search field.
3. Press esc — the picker stays open and no key dismisses it.
