-- Migrate the OAuth/OIDC *provider* feature from the deprecated
-- `oidc-provider` plugin to `@better-auth/oauth-provider`.
--
-- Tables: oauth_applications -> oauth_clients, oauth_access_tokens reshaped,
-- new oauth_refresh_tokens, oauth_consent -> oauth_consents, plus a `jwks`
-- table for the `jwt` plugin (id_token signing keys).
--
-- Data preservation:
--   * Registered clients are copied from oauth_applications into oauth_clients,
--     converting the legacy comma-separated `redirect_urls` into the JSON
--     string[] (`redirect_uris`) the new adapter expects.
--   * Access tokens and consent records are NOT migrated: access tokens are
--     short-lived (and the column shape changed entirely), and consents are
--     cheaply re-granted on next authorization. Both old tables are dropped.
--
-- NOTE: legacy client secrets were stored in plaintext, whereas the new
-- provider stores them hashed. Migrated client secrets will therefore not
-- validate as-is — affected applications must rotate their secret after
-- upgrade.
