Swap demo to Track0000 — my own unfinished song from 2016

Replace the placeholder demo clip with Track0000, the song I recorded in
2016 and never finished — the exact kind of clip CODA exists to finish, and
the emotional core of the project. Update the demo button + footer to tell
that story; remove the old placeholder. Bundled via Git LFS.
