Squash the pre-production migration history into fresh core, fedwiki,
and stripe baselines and reduce the canonical source list to those
three streams.
Update sqlc configs, generated queries, raw SQL, tests, and docs while
keeping provider tables schema-qualified.
BREAKING: existing local database volumes must be wiped because goose
version history restarts from the new baselines.
Add entitlement_sets and entitlement_set_rules with seed data and a
migration that backfills products, grants, and pool_provisions, then
removes product_entitlement_rules. Update Go models, sqlc queries,
materialization, and grant/provision flows to use entitlement_set_id.
Fix assembleMigrations to assign stable per-module numeric namespaces.
Move DB docs to docs/database-management.md and add design/specs/tests.
