"""Idempotent development seed.

Run with ``pnpm db:seed``. Creates a platform owner, a demo user, a sample
organization that both of them own, the system agent templates, routing
policies, rate cards and a mock provider with two models.

Safe to run repeatedly: every step checks for existing rows first.

The two accounts it prints at the end are meant to be usable immediately —
``tests/test_seed.py`` asserts exactly that, because a seed whose credentials the
login endpoint rejects is worse than no seed at all.
