Instrument the Echoly extension with the same PostHog project the website uses (echolyhq.com), so we can see real usage — most-Started voices, popular target languages, realtime vs standard split, and open→dub funnel. - analytics.js: tiny MV3-safe PostHog client. MV3 CSP forbids the posthog-js CDN and there is no bundler, so it POSTs straight to the capture endpoint from the service worker. Anonymous: random distinct_id in storage, no email, no Kyma key, no provider/routing detail; person profiles disabled. - background.js: emit extension_installed/updated, dub_started, dub_failed, dub_stopped (with duration). All session events route through the SW. - popup.js: emit popup_opened via a TRACK passthrough message. - manifest.json: add us.i.posthog.com host permission; bump 0.6.3 -> 0.6.4. Verified: capture endpoint returns HTTP 200; JS/JSON syntax checks pass. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

What
Cắm PostHog vào extension, dùng chung project với website (echolyhq.com) để có số liệu sử dụng thật.
Why
Trả lời được các câu cụ thể: giọng nào được Start nhiều nhất (mục tiêu rút gọn top 3 voices), ngôn ngữ đích phổ biến, tỉ lệ realtime vs standard, và funnel mở popup → dub.
