cards-server: switch from `bun run --watch` to `bun run --hot`.
--watch restarts the whole process on file change, racing the
old + new Bun.serve calls for the port (the EADDRINUSE you see
right after `listening on :3072`). --hot does in-process HMR via
the globalThis[hmrSymbol] pattern; the port stays bound across
reloads. apps/api already uses --hot for the same reason.
scripts/setup-databases.sh:
- create_db_if_not_exists "mana_notify" + "mana_credits" so a
fresh-machine `pnpm setup:db` no longer leaves these two DBs
off (mana-notify was crashing on boot with SASL fallback,
mana-credits was less obvious because its drizzle config
defaults to mana_platform — but the runtime config can point
at mana_credits, so safer to have the DB exist).
- Fix the cards branch: was pointing at the non-existent
@mana/cards-database package; now points at @mana/cards-server
where the actual schema lives.
Verified: drop+re-create flow + cardecky:full boot + touch-trigger
hot-reload all clean.
