The reasoning model truncated replies before the end-of-reply [HP-N]
tag, so damage was never reported and HP stuck at 100. Move the tag to
the FIRST line of the reply so it survives truncation, and clarify the
wording (concrete example numbers instead of the literal "[HP-N]" that
confused the model).
Also make the seeder the source of truth for demo content: it now
reconciles an existing seeded scenario in place when a seed file
changes (keeping the scenario row and its adventure FKs), instead of
only inserting when missing — otherwise fixes to already-seeded demos
never reach production. No-op when content already matches, so it stays
cheap on every boot.
Verified end-to-end through the quickjs engine, including a truncated
reply still applying damage, and the in-place update path.

Idempotent seeder inserts public, unowned demo scenarios from
backend/app/seed_data/*.json if a public scenario with the same title
is missing, so a fresh Neon database (and any clone) gets demo content
guests can play immediately. Ships two scenarios: the Sunken Crypt of
Vharos (all four script hooks) and Signal from the Derelict (sci-fi,
context-engine focused).
