Subject: [PATCH] feat: add severity-based TTL defaults for toast notifications

Info/success toasts auto-dismiss faster (3.5-4s) while warn/error
toasts persist longer (8-10s). Callers can still override with
explicit ttlMs. Dedupe, cooldown window, and MAX_TOASTS cap were
already in place from Phase 1.
