CDP-injected cookies lost on graceful exit

[XDLCS]

Steps to reproduce

1. Start the automation server with a cookie file:

touch cookies.tsv   # empty file, TSV format
moli serve --port 9333 --cookie-file cookies.tsv

2. Via CDP: navigate to any page, then Network.setCookie {name: "c1", value: "v1", url: "http://127.0.0.1/..."} — returns success: true, and the cookie is visible via document.cookie.
3. Also set a cookie from JS: document.cookie = 'c2=v2; path=/' — visible in-session.
4. SIGTERM the server (graceful exit) and inspect cookies.tsv.

Expected

Both cookies are persisted, as page-network-stack Set-Cookie cookies are.

Actual

cookies.tsv is empty after the graceful exit — CDP-injected and JS-set cookies are both lost. Network-stack Set-Cookie cookies from page loads persist correctly, so the persistence layer itself works.

Impact

Agent login flows that seed cookies via CDP lose state across restarts.

Suggestion

Route CDP-injected and document.cookie writes through the same persistence path as network-stack Set-Cookie.

Environment

• moli 1.1.10 (9b2f86b), Linux, serve + CDP
