intl 0.1.3

Pure-Rust, no_std internationalization primitives (a pure-Rust ICU analog). The `unicode` module provides General_Category, character predicates, scripts, East Asian Width, numeric values, case mapping/folding, UAX #15 normalization (NFC/NFD/NFKC/NFKD), and UTS #10 collation — property tables compiled into const-fn match lookups, with feature-selectable codepoint ranges.
