Replaces the URL-only placeholder extension with a full MV3 page-clipper
that builds a self-contained EPUB on the user's machine and uploads it
to the inbox.
- Captures the rendered DOM in a content script, then runs Readability,
asset bundling, and EPUB build through the shared
`convertToEpub({kind: 'page'})` pipeline inside a Chrome offscreen
document (the SW lacks DOMParser).
- Uploads the resulting EPUB directly from the offscreen page to the
new `POST /api/send/inbox/file` endpoint — keeps the bytes in one
realm because `runtime.sendMessage` JSON-serialises ArrayBuffer to
`{}` between extension contexts.
- Adds a long-lived Port + ping handshake between SW, offscreen, and
the on-demand capture content script so neither idle-eviction nor
load-order races can hang the popup.
- Localised popup, badge feedback, key-as-content i18n (`_('English source')`)
with an extract script that seeds locale stubs from i18n-langs.json
and writes a static-imports map for the runtime. All 33 locales
fully translated.
- Server: `pages/api/send/inbox/file.ts` accepts a raw EPUB body
(Content-Type: application/epub+zip), enforces the inbox pending cap,
stores to the existing send-inbox R2 bucket as `kind='file'`.
`assetBundler` now sets `credentials: 'include'` in the non-Tauri
branch so the extension SW carries paywalled-CDN cookies.
- 47 vitest cases for the extension shell (upload, badge, auth, lazy,
popup state machine, auth-bridge token sync) + 8 cases for the new
server endpoint. CI's `test_web_app` invokes both via the extended
`test:pr:web` plus a `build-browser-ext` step that catches webpack
alias / Tauri-stub regressions.
