• feat(types): new parseInterpolation TypeOption (default true). When set to false in CustomTypeOptions, the type-level extractor stops parsing translation strings for {{variable}} patterns. Required by i18next-icu users — the default extractor mistakes ICU MessageFormat nested-brace plurals like {count, plural, one {{count} row} other {{count} rows}} for an interpolation block and demands a phantom variable name. The flag is type-only; runtime interpolation is governed by InterpolationOptions and is unaffected. Fixes i18next-icu#85.
• fix(types): expose enableSelector on InitOptions so i18next.init({ enableSelector: 'strict' }) typechecks without a module augmentation. The runtime already reads opts?.enableSelector from init options; this lands the matching type declaration next to the other selector-resolution knobs. Accepts false | true | 'optimize' | 'strict'.
