* Block P1 — Password reset flow.
*
* Public surface:
* - generateResetToken()
* - createPasswordResetRequest() → always { ok: true }
* - consumeResetToken()
* - inspectResetToken()
*
* Security:
* - Plaintext token NEVER persists; we store only SHA-256(token).
* - createPasswordResetRequest never reveals whether the email exists.
* - consumeResetToken rotates the password AND drops every session.
