feat: seed /public/links.jsonld on first run (#13)

After sign-in, the new /public/ tile on the welcome page used to land
the user on an empty container (just an LDP listing of the .acl file).
This adds a small JSON-LD doc with a couple of useful outbound links —
Pilot (Solid app to use) and a directory of more Solid apps — plus
the jspod / JSS source repos.

Skip-if-exists, so user customizations to /public/links.jsonld
survive jspod restarts. Lives alongside the existing welcome.html
overwrite logic; both fire after waitForReady resolves.

The data browser renders the file as a cream-card with each URI as
a clickable link — the page is the data, the data is the navigation.

Bumps jspod to 0.0.15.
