chore: bump i18next from 26.3.4 to 26.4.0

[dependabot]

Bumps i18next from 26.3.4 to 26.4.0.

Release notes

Sourced from i18next's releases.

v26.4.0

• perf: cache toResolveHierarchy results per (code, fallbackCode) pair. The hierarchy resolver runs on every t() call and calls Intl.getCanonicalLocales multiple times, which showed up prominently when profiling render-heavy UIs (e.g. virtualized data grids); with the cache the per-call cost drops from ~886 ns to ~41 ns. The cache is invalidated automatically when options.fallbackLng changes (reassignment or in-place array mutation); if you mutate other resolution-relevant options at runtime (load, lowerCaseLng, cleanCode, nonExplicitSupportedLngs), call i18next.services.languageUtils.clearCache() afterwards. Function-valued fallbackLng and per-call array/object fallbackLng options are never cached, so dynamic fallbacks keep working as before. Thanks @​equaterina (#2444).
• chore: update all devDependencies (Babel stays on 7.x until @rollup/plugin-babel supports 8, eslint on 9.x for neostandard). Removed the unused coveralls package (CI uses the Coveralls GitHub Action) and replaced sinon with nise + vitest.spyOn in the v1 compatibility tests, which resolves all open npm audit findings (0 vulnerabilities) and should close the dependabot alerts on the lockfile.

v26.3.6

• fix: allow TypeScript 7 in the optional typescript peer dependency range (^5 || ^6 || ^7). With typescript@7.0.2 in a project, npm install failed with an ERESOLVE peer conflict. The published types are TS7-compatible as-is: every test/typescript suite produces identical results under 6.0 and 7.0.2. Reported in react-i18next#1927, thanks @​andikapradanaarif.

v26.3.5

• fix: $t() nesting options blocks that span multiple lines are now parsed. nest() decided where the nested key ends by testing match[1] with /{.*}/, whose dot does not cross line breaks — so a $t(key, { ... }) options object containing a newline was treated as having no options, mis-split as formatters, and the nested lookup ran without its options (placeholders stayed unresolved). The nesting regexp itself already matches newlines inside $t(...); adding the s (dotAll) flag makes multiline options behave like the single-line form. Thanks @​spokodev (#2440).
• fix: getUsedParamsDetails (the returnDetails: true path) no longer mutates the passed replace object. It wrote count straight onto options.replace so the returned usedParams would include it — a caller reusing one replace object across t() calls then carried a stale count into later interpolations (e.g. a previous call's count: 5 rendered instead of the current call's value). The details are now built from a copy; usedParams still includes count. Thanks @​spokodev (#2441).
• fix: with the default skipOnVariables: true + escapeValue: true, a {{placeholder}} carried inside an interpolated value now stays literal even when the value contains escapable characters. The skip logic advanced the regex lastIndex by the raw value length, but the escaped text written into the string is longer, so lastIndex landed inside the inserted value and a trailing {{placeholder}} in it got interpolated — leaking another in-scope variable that should have stayed literal (values without escapable characters were already skipped correctly). The advance now uses the escaped length that is actually written, and the regex-safe $-doubling is applied only at the String.replace call so it can't distort the length arithmetic. Thanks @​spokodev (#2442).
