feat(models): 'ox alpha' now finds x-preview-f-free in every model picker

The OpenCode Zen wire slug for the Ox Alpha stealth model is opaque
(x-preview-f-free); users searching the picker for 'ox' or 'ox-alpha'
found nothing. Adds the search alias across all four synced alias
tables (CLI, desktop, web, TUI) plus tests. Wire id is unchanged and
still what renders and gets sent to the provider, matching the k3 →
kimi-k3 precedent. No canonical-dedup collision with opencode-go's
keyed ox-alpha-free slug.
