* Move the e2e suite to Go and playwright-go

The seven playwright tests in `frontend/e2e` become twenty in `e2e/`, a
separate Go module driving the same browsers through playwright-go. The
npm project, its lockfile entries, its prettier config and
`Dockerfile.e2e` go with it, leaving `frontend/` a single-member
workspace.

The suite covers posting with markdown, replying and the nesting that
implies, editing inside the deadline and the backend refusing one outside
it, deleting, voting with the optimistic score observed mid-flight and
rolled back on failure, changing the sort, collapse persistence across a
reload, dev, anonymous and email sign-in end to end, the profile iframe,
and the two scripts that render into the host page rather than the
widget's own frame.

The rendering tests run in chromium, firefox and webkit. The rest sign in,
sign-in needs the dev oauth2 provider, and reaching that by name from the
host is chromium-only, so they run there alone.

`compose-e2e-test.yml` runs remark42, a second instance with a short edit
window so that path does not need a five-minute test, and mailpit, which
catches the email verification message the suite reads back. Everything
binds to the loopback interface: the stack holds a known secret and an
admin shared id, and `go test` can start it unattended. The tests run on
the host rather than in a container.

Three settings there exist for the tests rather than for realism.
`REMARK_URL` uses a hostname because the dev oauth2 server binds whatever
host it reads out of it, and a loopback bind inside a container cannot be
published. `UPDATE_LIMIT` is raised because the default of 0.5/sec rejects
any test posting twice in a row. The suite also paces its own `/auth/`
calls, which are capped at 2/sec by a bare literal in `rest.go` rather
than by a setting.

Each test gets its own comment thread from a query string on the demo
page, so nothing has to reset the database between runs.

CI gains a vet and lint job for the module, since the build tag keeps it
out of a plain `go test ./...`, and uploads a browser trace for any test
that fails.

`e2e/README.md` carries the rest: how to run it, what the stack is for,
and the widget behaviour the assertions have to work around.

* Update golangci-lint to 2.13.1 in the backend workflow

The pin sat three minors behind what the linter installs locally, so CI
checked the backend with an older set of rules than anyone running it by
hand. 2.10.1 also fetches its config schema over the network on every
`config verify`, which is a failure mode with no bearing on the code.

Both targets are clean on 2.13.1, `backend/app` and the memory_store
example.
