v1.8.0 — i18n (English + Spanish UI)

Adds English + Spanish UI via chrome.i18n — the popup now follows your browser language (English by default, Spanish for es locales).

This re-implements the i18n proposal from @adc103 (#1) on the current popup; the original PR predated the 1.5–1.7 rewrite and no longer applied cleanly. Thanks @adc103 for the approach! 🙏

Everything from v1.7.0 is included (captures again, async OPFS, pause/resume, real LinkedIn preset, download site cookies).

Install: download api-reverse-engineer-1.8.0.zip, unzip, then chrome://extensions → Developer Mode → Load unpacked → select the folder.
