build: run the browser e2e suites in CI (closes #259)

Nothing automatic ran either e2e suite, so every browser-level guarantee in this
wallet -- WebAssembly under the shipped CSP, the recovery-phrase and private-key
DOM wipes, the ConfirmTx spend gate, the dApp approval round trips -- held only
when a human or an agent remembered to run it by hand.

.gitea/workflows/e2e.yml adds two jobs, e2e-chrome and e2e-firefox, one per
browser so a Chrome failure cannot hide the Firefox result. They are separate
from the check workflow: REPO_POLICIES.md caps make test at 20 seconds and
script/cibuild is a docker build whose Dockerfile runs make check, so neither the
cap nor the local fast path is touched. make check is byte-for-byte unchanged.

Neither suite could run on the runner as it stood, and the reason is not
docker-in-docker. The runner executes a job inside a container against the HOST's
docker daemon, and the job's checkout lives on a docker volume rather than a host
path, so `docker run -v "$PWD:/work"` is resolved by the host, silently succeeds
and mounts an empty directory -- measured on this runner. The runner image's node
is also too old to install this repo's dependencies. Both suites therefore ship
the repo to the daemon as a build context and build the extension inside the
pinned image, which leaves docker as the only prerequisite on a runner or a
laptop. The suites themselves are unchanged; only how the repo reaches the
container is.

Both scripts now build with --iidfile and run the image by ID rather than by tag,
so two clones running a suite at once on the same host cannot swap it under each
other.

The jobs report, they do not gate. Whether a check blocks a merge is Gitea branch
protection, which this repo does not configure, so a failure is a red mark a
reviewer must account for. Nothing can pass vacuously: no continue-on-error, no
`|| true`, and both scripts exit non-zero when docker is missing, when the image
build fails and when the browser fails to start.

Wiring this up measured something that has to be said rather than absorbed: the
Chrome suite is flaky under load. Two of six runs of unmutated code on a loaded
machine lost the approval popup out from under the dApp signing wait. It is
filed as #287 and not papered over here -- no retry wrapper, no longer timeout,
no weakened assertion -- and it is the reason e2e-chrome cannot become a
required check yet. README and the workflow say so where a reader meets them.

+checkout and the matching `script/` entrypoint, nothing else.
+
+Docker is the only thing either job needs from the runner, and that is not an
+accident. The runner executes a job inside a container against the **host's**
+docker daemon, so a `docker run -v "$PWD:/work"` source path is resolved by the

+**measurably flaky under load** — two of six runs of unmutated code on a busy

+making this a required check. Do not answer it with a retry wrapper: a suite
+that reruns until it is green stops being evidence.
+
+Nothing in either job can pass vacuously. There is no `continue-on-error` and no

+build fails, and when the browser fails to start; the Chrome harness aborts the
