onHeadersReceived (where shouldCapture runs) doesn't carry the headers the
browser actually sent; signed-URL and referrer-gated CDNs need them. Stash
from onBeforeSendHeaders keyed by requestId, read back at capture time.
This map sees every request, so it is bounded both ways — oldest-out past a
size cap (default 2048) and a 5-minute TTL, swept on a 60 s timer and on read
— and attach() clears an entry the moment its request completes or errors.
normalizeHeaders(): Array<{name,value}> -> lower-cased map, repeats joined
with ", ". 13 tests: eviction order, redirect re-put refresh, TTL expiry,
sweep, and the onBeforeSendHeaders/onCompleted/onErrorOccurred wiring.

Build against tools/mockd over the WebSocket transport; veloxd is not required.
Transport quick start
import { createTransport } from './src/background/transport/index.js';
const t = await createTransport(); // reads the Options override; default 'auto'
t.onStateChange((s) => renderDot(s));
const rules = await t.call('capture.getRules', {});
createTransport resolves with a live, self-reconnecting transport. When veloxd is not
up yet it still resolves (WebSocket, status disconnected, retrying) — callers render the
red dot. It rejects only when the user explicitly forced native messaging and that failed.
Capture code treats every call() rejection as fail-open.
