Covers render in the userscript panel, from a public route (#60) (#69)

Closes #60.

Spec: #55. Originating bug: #47. Architecture: `docs/adr/0007-backend-hosts-cover-bytes.md`. Neither #47 nor #55 is closed from here.

## What this branch does

The panel now renders Covers from the deployment's own origin, and both userscripts stop having an opinion about where a Cover lives.

**The public route was already in place.** `GET /covers/{address}` landed with #59 (`92eba07`) and is registered on the bare mux, outside `httpmw.Auth` and outside the web UI's Discord session — `backend/main.go:210-214`, handler `backend/internal/api/handlers.go:142-158`. It reads no cookie and no header, answers `404` for an address that was never stored (and for a row whose file has gone missing — recorded-but-gone is not-found, never a fabricated body), refuses anything that is not `^[0-9a-f]{64}$` *before* the value becomes a path, and sets `Cache-Control: public, max-age=604800, immutable`. Those four properties are asserted by `backend/cover_test.go:231-278`. This branch re-verified them rather than re-implementing them; the only backend line it touches is a comment.

**Both userscripts lose cover scraping entirely.** Every adapter's `cover:` field is gone, along with the two helpers that fed them: the manga script's `coverFromPage()` (the `img[alt]` DOM scan comix needed, because comix publishes no `og:image`) and the novel script's `metaName()` plus the now-callerless module-level `meta()`. Nothing under `userscript/` reads `og:image`, `meta[name=image]`, or `img[alt]` any more.

**Nothing sends a cover either.** `delete body.cover` sits in `apiPut` — `manga-bookmark.user.js:486`, `novel-bookmark.user.js:275` — which is the single chokepoint every write passes through (`pushBookmark`, the retry-queue flush, `toggleFavorite`, `toggleArchive`). It operates on the `Object.assign` copy, so the in-memory row keeps the cover it renders with. This matters beyond tidiness: a Reader upgrading from an older copy has `localStorage` rows carrying third-party scraped URLs, and without the strip those would ride back up on the next write. The handler discards the field regardless (`handlers.go:53-59`) — it is permanently inert, not pending removal.

**Failed loads get the designed empty state, not the broken-image glyph.** `onerror: (e) => e.target.replaceWith(el("div", { class: "cover ph" }))` on the cover `<img>` in both card renderers (`manga:1380-1390`, `novel:1134-1144`). The replacement is byte-identical to the existing no-cover branch on the very next line, so it picks up the `.cover.ph` styling already in the panel CSS — no new tokens, no new rule. `el()` routes any `on*` prop through `addEventListener`, so this is a listener, not an inline attribute string, and the swap is a `createElement` + DOM call with no markup parsing anywhere near it. This is the half of #47 that was visible on kagane.

**The deleted scraping's tests went with it**: the two comix cover cases, the `pageImages` and `namedMetas` fixtures, the `img[alt]` and `meta[name=...]` stub branches, the now-dead `querySelectorAll` stub member, and every stale `og:image` fixture and `p.cover` assertion across both suites. The export lists needed no change and that was checked, not assumed — `coverFromPage` and `metaName` were module-private on `origin/main` and no cover symbol ever appeared in `module.exports`.

Docs that described the deleted behaviour were corrected in the same breath, because leaving them would instruct the next agent to put the scraping back: `userscript/AGENTS.md` (adapter contract + the per-site notes for comix, kagane and novelfull), the README's adapter reference, and the userscript testing skill's stub table.

## Verification

- `go test -count=1 ./...` — green across all nine packages (`backend` 29.8s, `latest`, `store`, `session`, `token`, `userscript`, `web`).
- `node --check` clean on both userscripts; `node --test` on both logic suites — 46 tests, 46 pass.
- `gofmt -l` clean; `go build ./...` clean.
- The `onerror` swap is DOM behaviour and deliberately has no coverage in the Node harness — that harness stubs a browser precisely so it never needs a DOM, and #60 says not to invent coverage for it. It was instead exercised for real: the `el()` helper and the exact render expression were loaded into a headless Chromium with a deliberately unloadable `src`, and the resulting DOM was `<div class="cover ph"></div>`. Ad hoc, not committed.
- **Not done, needs you:** the on-device criterion — a comix Series bookmarked mid-chapter showing its Cover in the panel. That needs a real install against the deployment and is the one box left unticked on #60.

## Reviewed

Both `/code-review` axes ran against `cc0fa92`. Spec found no missed requirement and no scope creep; standards found the diff clean on the four areas it scrutinised (the `delete body.cover` placement, the `onerror` handler's DOM safety, comment quality, dead-code removal). Their combined findings — the dead `querySelectorAll` stub, the stale README and skill text, and the handler comment whose premise this change invalidates — are fixed in `8b58019`.

## Out of scope, deliberately

The kagane-specific cover proxy still exists and still carries its session gate (#63 deletes it). The poll's blank-Cover fill (#61) and browser-backed Sites joining the pipeline (#62) are untouched.
