test: containerized Firefox end-to-end harness (closes #184)

Drives the real popup in a real Firefox with dist/firefox/ installed as an
unpacked MV2 temporary add-on, via geckodriver. Covers popup load, wallet
creation through the UI, and the Add Token screen. Outside make check, like
the Chrome suite.

Zero npm dependencies: tests/e2e/firefox/driver.js is a WebDriver client
over global fetch and child_process against geckodriver's HTTP API. The
Dockerfile pins the node base image, the Firefox 153.0.3 tarball and
geckodriver 0.36.0 by digest.

Errors are read from the privileged nsIConsoleService in Marionette's chrome
context, filtered to non-warning entries whose sourceName is the extension
origin. BiDi log.entryAdded delivers nothing at all for extension pages, so
a Playwright-BiDi or Puppeteer-BiDi harness would see nothing and report
success; the code says so where someone would be tempted to simplify it.
Errors logged during add-on install and background startup are drained and
folded into step 1, never discarded: a throw at the top of
src/background/index.js kills the background page and fails the run.
Content-script capture is left as unverified, because --network none leaves
no http:// page for a content script to be injected into.

Each drain reads the console and clears it in ONE chrome script. Splitting
the read from Services.console.reset() left a window between the two round
trips in which an error was logged into a buffer about to be discarded, and
destroyed unread rather than deferred to the next drain; a probe of 100
sequenced throws at 20ms spacing lost one. With the drain atomic the same
probe accounts for every throw that falls inside the observed window, on two
consecutive runs.

No driver layer is shared with the Chrome suite and the three UI steps are
written twice deliberately: the two backends have no common substrate, and
three steps do not pay for a shim.

Two limits are documented rather than papered over, with measurements rather
than absolutes. Error capture is poll-based, so an error is attributed to a
step and not to a moment within it; the drained window ends ~1.5s after the
last step returns (a 500ms settle, a 1000ms sleep and two drain round trips),
and that cut-off jitters run to run — three runs of throws at fixed offsets
reported everything up to +1.5s and one of the three also reported +1.6s.
Inside the window the atomic drain leaves no race, but nsIConsoleService
keeps a ring buffer of only 250 messages, so more than 250 console messages
between two drains evicts unread errors: 400 throws inside one step report
as exactly the newest 250, on three runs, while occupancy in a clean run
peaks at 4 of 250 at the install drain and 0 at every later drain. Nothing is
stubbed; the container runs with --network none instead, which proves no
request escaped, cannot report which were attempted, and runs only the
failure branches of network-dependent code.

 # Completed Steps
 
-- 2026-08-14: `make check` does static analysis. `script/lint` ran
-  `prettier --check .`, byte-identical to `script/fmt-check`, so a wallet with
-  two shipped used-but-not-imported crashes behind it was green. ESLint is now
-  pinned in `package.json` with `@eslint/js` recommended as the base, flat
-  config in `eslint.config.js`, `no-undef` and `no-unused-vars` error-level, and
-  globals declared per tree — browser for the popup and content scripts, service
-  worker for `src/background/` and `src/shared/`, jest for `tests/`, node for
-  `build.js`. It found 41 unused bindings and 53 undefined identifiers; all are
-  fixed, and dropping a call to an unimported `foo()` into any `src/` file fails
-  `make lint`. Linting is also containerized now: `script/lint` builds the
-  Dockerfile's new `lint` stage, so the ESLint that decides whether this repo is
-  green is the pinned one and not the host's
-  ([#152](https://git.eeqj.de/sneak/AutistMask/issues/152)).
-- 2026-08-12: EIP-1193 error codes now reach the page. `src/content/inpage.js`
-  rebuilt every failure as `new Error(error.message)`, so the code the
-  background produced and the content script relayed intact was dropped in the
-  last hop and a dApp checking `err.code === 4001` saw `undefined` — a wallet
-  the user deliberately declined was indistinguishable from one that broke. The
-  provider now rejects with a `ProviderRpcError` carrying `code` and, where the
-  boundary sent one, `data`, passed through verbatim rather than matched against
-  a list, so 4001, 4100 and 4902 all arrive and a future code needs no edit
-  here. An error the background sent with no code stays a plain `Error` with no
-  `code` property, and `message` is unchanged in every case. All four request
-  entry points (`request`, `enable`, `send`, `sendAsync`) are covered by
-  `tests/inpageErrors.test.js`, and the e2e probe that printed the missing code
-  now requires it on the page's Error as well as on the wire, for all four
-  rejected flows ([#274](https://git.eeqj.de/sneak/AutistMask/issues/274)).
-- 2026-08-12: "Back" now renders the screen it lands on instead of only unhiding
-  it. A reopened popup renders the wallet list and the one screen it restores
-  onto, so every screen further down the stack was still the blank template from
-  `index.html`, and Back walked straight onto it — an empty address, no
-  balances, no QR code. The Back path now goes through the same per-view
-  dispatch and data guards as the restore (`src/popup/viewRouter.js`, shared
-  with `restoreView()`), falling back to Home when the state the target would
-  render is gone. It renders only a view this page load has not rendered yet:
-  `viewRouter.js` records every view that reaches `showView()`, which is where
-  forward navigation and the restore both end, so Back onto a view already on
-  the page unhides it and nothing more. That is what keeps a second render from
-  re-fetching and overwriting what the view holds — an unsaved edit in Settings,
-  a transaction list already loaded. Home is the exception and is always
-  re-rendered, as it was before. Covered by unit tests on the real `goBack()`
-  and by three end-to-end cases against the real popup, each demonstrated
-  failing on the unfixed build
-  ([#268](https://git.eeqj.de/sneak/AutistMask/issues/268)).
-- 2026-08-12: `KNOWN_SYMBOLS` now maps a symbol to the set of contract addresses
-  that bear it, not to one of them. A ticker is not unique: seven of the 512
-  bundled tokens — `FRAX`, `REUSD`, `TON`, `EURE`, `MSUSD`, `MUSD` and `JPYC` —
-  share a symbol with another bundled entry at a different real contract, and
-  the table, built from the list first-wins, kept only the earlier one. The
-  other seven were judged spoofs of their own symbol at their own address and
-  hidden from the balance list, the history and the send selector, so a holder
-  could not spend them. Both contracts of each pair come from the same CoinGecko
-  fetch of 2026-02-27, so neither was stale and neither was dropped.
-  `isSpoofedSymbol()` asks set membership instead of equality, which does not
-  loosen the rule — a contract outside the set is still a spoof — and a test now
-  walks `TOKENS` asserting no bundled token is filtered at its own address,
-  which is the walk the suite lacked
-  ([#276](https://git.eeqj.de/sneak/AutistMask/issues/276)).
-- 2026-08-12: The dApp approval round trips are driven end to end in the
-  browser. A test page served by the harness speaks EIP-1193 to the real inpage
-  provider through the real content script, background worker and approval popup
-  for `eth_requestAccounts`, `personal_sign`, `eth_signTypedData_v4` and
-  `eth_sendTransaction`. Every signature is recovered and compared against the
-  active address, the transaction is checked against the bytes handed to the
-  stubbed RPC, each rejection must reach the page as a rejection, and the
-  password must appear in no message the approval window sends — the assertion
-  that gives [#157](https://git.eeqj.de/sneak/AutistMask/issues/157) a permanent
-  floor. This does not discharge a real dApp with real funds against mainnet
-  ([#183](https://git.eeqj.de/sneak/AutistMask/issues/183)).
-- 2026-08-12: The known-symbol spoof rule now judges the symbol a user actually
-  sees. `isSpoofedSymbol()` normalizes before the lookup — NFKC, then every
-  character that paints nothing removed (the format and default-ignorable
-  characters, plus U+007F), then trimmed — so `" ETH "`, a no-break space, a
-  zero-width space, a Hangul filler, a variation selector, a DELETE and a
-  fullwidth `ＥＴＨ` are all caught on the balance list, the history and the
-  send selector at once. Confusables that are distinct letters (Cyrillic `Е`),
-  bidi reordering and the visible C0/C1 controls — which measure 48.00px, a box,
-  in the pinned e2e Chromium where an invisible prefix measures 32.00px — stay
-  knowingly open and are asserted as open in the suite. No bundled symbol
-  contains whitespace or a non-ASCII character, so nothing legitimate is newly
-  filtered; the balance list's token-type gate also became case-insensitive,
-  which no longer drops a real holding if an explorer writes `erc-20`
-  ([#260](https://git.eeqj.de/sneak/AutistMask/issues/260)).
