…tch loop

Instantiate codeBlob and mapBlob once per file outside the batch loop
instead of re-creating new Blob instances on each batch slice. Blobs are
immutable, read-only binary handles and can be safely shared across
multiple worker batch tasks concurrently.

…nliner

Streamline the asynchronous cache resolution in inlineAll by removing
the intermediate CacheCheckItem interface and array mapping allocations.
Results are now assigned directly to fileResultsByLocale on hit or pushed
to uncachedByFile on miss. When no persistent cache is configured, a fast
path directly queues uncached files without promise or hash overhead.

…ing in i18n inliner

Introduce generation tracking in I18nInliner and worker batch tasks to
guarantee long-term worker caches (fileDataCache and deserializedTranslations)
are wiped whenever a new inlining pass or rebuild begins (e.g. watch mode
or shared worker pools).

…n i18n inliner worker

Consolidate the 3 chained string replacement passes (unescaping double quotes,
escaping backticks, and escaping ${ delimiters) into a single regex pass in
escapeTemplatePart. This eliminates 3 intermediate string allocations and
reduces 3 regex scans to 1 on every translated template literal part.
