build(deps): bump i18next-http-backend from 3.0.6 to 4.0.2

[dependabot]

Bumps i18next-http-backend from 3.0.6 to 4.0.2.

Changelog

Sourced from i18next-http-backend's changelog.

4.0.2

Security release. See advisory GHSA-xvq9-wjp8-hwqf.

• security: also reject : in lng and ns values, and // in ns values. With a loadPath / addPath template that starts with the placeholder (e.g. {{lng}}/{{ns}}.json — no origin and no leading /), a value such as http:127.0.0.1:8080 was interpolated into an absolute URL and the request left the intended origin (SSRF / URL injection). The default /locales/{{lng}}/{{ns}}.json and every template with a leading path or origin were not affected, because a colon inside a path segment has no structural meaning there. No BCP-47 language code contains :, and : is i18next's default nsSeparator, so no usable namespace name does either — the tightened check has no legitimate collateral.

4.0.1

• fix: allow @ in ns values so scoped-package-style namespace names such as @organization/package-name fetch correctly again (#191). 3.0.6 relaxed the ns check for / but left @ in the shared denylist. In the URL path position @ is a plain RFC 3986 pchar with no structural meaning; it stays blocked for lng, where it marks the userinfo/authority boundary. Every other pattern from the 3.0.5 advisory (.., \, %, ?, #, whitespace, control chars, prototype keys, oversized inputs) remains blocked for both keys.

4.0.0

• BREAKING: drop cross-fetch dependency. i18next-http-backend now requires a host-provided fetch. This is available in Node ≥ 18 (stable since Node 21), all modern browsers, Deno, and Bun. For runtimes without native fetch, install a ponyfill yourself and inject it via options.alternateFetch, or stay on v3.x.
• BREAKING: minimum Node version is now 18 (engines.node = ">=18").
• chore: simplified environment detection in lib/request.js — uses globalThis (with global / window fallbacks for legacy embedded runtimes) instead of separate global.* / window.* branches per API. XHR / ActiveXObject are still picked up if the host provides them, but no longer polyfilled.
• chore: declared "sideEffects": false for better tree-shaking by downstream bundlers.
• build: replaced babel + browserify + uglify-js with tsdown (rolldown + oxc). One config produces ESM, CJS, and the IIFE browser bundles. Drops @babel/cli, @babel/core, @babel/preset-env, babel-plugin-add-module-exports, browserify, uglify-js, the fixcjs rewrite hack, and the --ignore cross-fetch browserify flag. Side benefit: minified browser bundle shrinks from ~13 KB to ~6.8 KB (oxc minifier + no babel runtime helpers).
• build: ESM and CJS outputs are now bundled into a single index.js per format (previously one file per lib/*.js module). The package's exports map is unchanged, so this is invisible to consumers using documented entry points.
• lint: replaced eslint-config-standard (+ five plugins) with neostandard and migrated to ESLint 9 flat config (eslint.config.mjs). Removed deprecated tslint and dtslint — test:typescript now runs tsc --noEmit plus tsd.
• chore: tightened .npmignore — published tarball no longer includes the source lib/, the build configs (tsdown.config.ts, eslint.config.mjs, tsconfig.json), or the root index.js re-export shim. Drops from 21.3 KB → ~17 KB packed.
• docs: alternateFetch is now documented in the README options block as the supported escape hatch for fetch ponyfills, test mocking, and request interception. v4 migration note added to "Getting started".
