Drop articles before renameable domain words (#51)

Apply SUBSTRATE-CONTRACT.md rule 1: UI strings and seed data must not
couple articles to renameable domain nouns (Shop, ItemTag, Shopkeeper),
so the agent's rename pipeline produces grammatical output for any
target word.

Mirrors nativeapptemplate/NativeAppTemplate-iOS#77. Of the 7 iOS UI
string changes, 3 have Android equivalents in strings.xml; the other
4 are toast/error strings that don't exist on Android. The seed
description fixtures (shop.json, shops.json) and the demo test that
mirrors them are updated to match.
