IndexedDB Test (exact match)

Imports en-words.txt into IndexedDB (one record per word). Measures fetch, parse, import, open time, and per-keystroke lookups using get() for exact membership checks. Clearing DB removes stored words, forcing fetch on next import.

Type a word to test (lookup runs on each input):

DB name: wordset-v1, store: words(w), meta: meta(k→v)
