Subject: [PATCH] demo mode: stop synthesizing episode + phase events
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Per the data-ownership scope: collect (episodes-ingested counter),
hosts (per-host bars), and db (database explorer) all work fine in
or out of demo mode — they read real values from the server's
snapshot. Demo mode shouldn't be injecting fake `episode` records
into them.

Removed both dispatches from demoTick:
- `episode` (was 70% per tick) — no longer clobbers collect/hosts/db
- `phase` (was 50% per tick) — dead code anyway; baseline now
  consumes the dataset-derived `phase_mix` event, not raw `phase`

demoTick is now just the model_metric jitter (5% per tick) so the
sequence-model bars don't sit frozen during a long demo.
